    Derivative Instruments and Hedging Activities Disclosure [Abstract]                                                 
        Derivative Instruments                                                                                          | Derivative instruments JPMorgan Chase makes markets in derivatives for clients and also uses derivatives to hedge or manage its own risk exposures. Refer to Note 5 of JPMorgan Chase’s 2020 Form 10-K for a further discussion of the Firm’s use of and accounting policies regarding derivative instruments. The Firm’s disclosures are based on the accounting treatment and purpose of these derivatives. A limited number of the Firm’s derivatives are designated in hedge accounting relationships and are disclosed according to the type of hedge (fair value hedge, cash flow hedge, or net investment hedge). Derivatives not designated in hedge accounting relationships include certain derivatives that are used to manage risks associated with specified assets and liabilities (“specified risk management” positions) as well as derivatives used in the Firm’s market-making businesses or for other purposes. The following table outlines the Firm’s primary uses of derivatives and the related hedge accounting designation or disclosure category.

Notional amounts(b) (in billions) September 30, 2021 December 31, 2020 Interest rate contracts Swaps $ 24,116 $ 20,990 (c) Futures and forwards 3,824 3,057 Written options 3,211 3,375 Purchased options 3,523 3,675 Total interest rate contracts 34,674 31,097 Credit derivatives(a) 1,340 1,197 (c) Foreign exchange contracts Cross-currency swaps 4,081 3,924 Spot, futures and forwards 8,268 6,871 Written options 803 830 Purchased options 791 825 Total foreign exchange contracts 13,943 12,450 Equity contracts Swaps 628 448 Futures and forwards 145 140 Written options 750 668 (c) Purchased options 704 610 (c) Total equity contracts 2,227 1,866 Commodity contracts Swaps 185 138 Spot, futures and forwards 195 198 Written options 149 124 Purchased options 122 105 Total commodity contracts 651 565 Total derivative notional amounts $ 52,835 $ 47,175 (a)Refer to the Credit derivatives discussion on page 126 for more information on volumes and types of credit derivative contracts. (b)Represents the sum of gross long and gross short third-party notional derivative contracts. (c)Prior-period amounts have been revised to conform with the current presentation. While the notional amounts disclosed above give an indication of the volume of the Firm’s derivatives activity, the notional amounts significantly exceed, in the Firm’s view, the possible losses that could arise from such transactions. For most derivative contracts, the notional amount is not exchanged; it is simply a reference amount used to calculate payments. Impact of derivatives on the Consolidated balance sheets The following table summarizes information on derivative receivables and payables (before and after netting adjustments) that are reflected on the Firm’s Consolidated balance sheets as of September 30, 2021, and December 31, 2020, by accounting designation (e.g., whether the derivatives were designated in qualifying hedge accounting relationships or not) and contract type.

Refer to Note 3 for further information. (b)As permitted under U.S. GAAP, the Firm has elected to net derivative receivables and derivative payables and the related cash collateral receivables and payables when a legally enforceable master netting agreement exists. (c)Prior-period amounts have been revised to conform with the current presentation. Derivatives netting The following tables present, as of September 30, 2021, and December 31, 2020, gross and net derivative receivables and payables by contract and settlement type. Derivative receivables and payables, as well as the related cash collateral from the same counterparty, have been netted on the Consolidated balance sheets where the Firm has obtained an appropriate legal opinion with respect to the master netting agreement. Where such a legal opinion has not been either sought or obtained, amounts are not eligible for netting on the Consolidated balance sheets, and those derivative receivables and payables are shown separately in the tables below. In addition to the cash collateral received and transferred that is presented on a net basis with derivative receivables and payables, the Firm receives and transfers additional collateral (financial instruments and cash). These amounts mitigate counterparty credit risk associated with the Firm’s derivative instruments, but are not eligible for net presentation: •collateral that consists of liquid securities and other cash collateral held at third-party custodians, which are shown separately as "Collateral not nettable on the Consolidated balance sheets" in the tables below, up to the fair value exposure amount. For the purpose of this disclosure, the definition of liquid securities is consistent with the definition of high quality liquid assets as defined in the LCR rule; •the amount of collateral held or transferred that exceeds the fair value exposure at the individual counterparty level, as of the date presented, which is excluded from the tables below; and •collateral held or transferred that relates to derivative receivables or payables where an appropriate legal opinion has not been either sought or obtained with respect to the master netting agreement, which is excluded from the tables below.

(b)Includes liquid securities and other cash collateral held at third-party custodians related to derivative instruments where an appropriate legal opinion has been obtained. For some counterparties, the collateral amounts of financial instruments may exceed the derivative receivables and derivative payables balances. Where this is the case, the total amount reported is limited to the net derivative receivables and net derivative payables balances with that counterparty. (c)Derivative collateral relates only to OTC and OTC-cleared derivative instruments. (d)Net derivatives receivable included cash collateral netted of $68.8 billion and $88.0 billion at September 30, 2021, and December 31, 2020, respectively. Net derivatives payable included cash collateral netted of $61.2 billion and $78.4 billion at September 30, 2021, and December 31, 2020, respectively. Derivative cash collateral relates to OTC and OTC-cleared derivative instruments. (e)Prior-period amounts have been revised to conform with the current presentation. Liquidity risk and credit-related contingent features Refer to Note 5 of JPMorgan Chase’s 2020 Form 10-K for a more detailed discussion of liquidity risk and credit-related contingent features related to the Firm’s derivative contracts. The following table shows the aggregate fair value of net derivative payables related to OTC and OTC-cleared derivatives that contain contingent collateral or termination features that may be triggered upon a ratings downgrade, and the associated collateral the Firm has posted in the normal course of business, at September 30, 2021, and December 31, 2020. OTC and OTC-cleared derivative payables containing downgrade triggers (in millions) September 30, 2021 December 31, 2020 Aggregate fair value of net derivative payables $ 19,541 $ 26,945 (a) Collateral posted 17,160 26,289 (a)Prior-period amount has been revised to conform with the current presentation. The following table shows the impact of a single-notch and two-notch downgrade of the long-term issuer ratings of JPMorgan Chase & Co. and its subsidiaries, predominantly JPMorgan Chase Bank, N.A., at September 30, 2021, and December 31, 2020, related to OTC and OTC-cleared derivative contracts with contingent collateral or termination features that may be triggered upon a ratings downgrade. Derivatives contracts generally require additional collateral to be posted or terminations to be triggered when the predefined threshold rating is breached. A downgrade by a single rating agency that does not result in a rating lower than a preexisting corresponding rating provided by another major rating agency will generally not result in additional collateral (except in certain instances in which additional initial margin may be required upon a ratings downgrade), nor in termination payments requirements. The liquidity impact in the table is calculated based upon a downgrade below the lowest current rating of the rating agencies referred to in the derivative contract. Liquidity impact of downgrade triggers on OTC and OTC-cleared derivatives September 30, 2021 December 31, 2020 (in millions) Single-notch downgrade Two-notch downgrade Single-notch downgrade Two-notch downgrade Amount of additional collateral to be posted upon downgrade(a) $ 230 $ 1,572 $ 119 $ 1,243 Amount required to settle contracts with termination triggers upon downgrade(b) 109 685 153 1,682 (c) (a)Includes the additional collateral to be posted for initial margin. (b)Amounts represent fair values of derivative payables, and do not reflect collateral posted. (c)Prior-period amount has been revised to conform with the current presentation. Derivatives executed in contemplation of a sale of the underlying financial asset In certain instances the Firm enters into transactions in which it transfers financial assets but maintains the economic exposure to the transferred assets by entering into a derivative with the same counterparty in contemplation of the initial transfer. The Firm generally accounts for such transfers as collateralized financing transactions as described in Note 10, but in limited circumstances they may qualify to be accounted for as a sale and a derivative under U.S. GAAP. The amount of such transfers accounted for as a sale where the associated derivative was outstanding was not material at September 30, 2021 and December 31, 2020. Impact of derivatives on the Consolidated statements of income The following tables provide information related to gains and losses recorded on derivatives based on their hedge accounting designation or purpose. Fair value hedge gains and losses The following tables present derivative instruments, by contract type, used in fair value hedge accounting relationships, as well as pre-tax gains/(losses) recorded on such derivatives and the related hedged items for the three and nine months ended September 30, 2021 and 2020, respectively. The Firm includes gains/(losses) on the hedging derivative in the same line item in the Consolidated statements of income as the related hedged item.

Gains and losses were recorded in net interest income. (b)Excludes the amortization expense associated with the inception hedge accounting adjustment applied to the hedged item. This expense is recorded in net interest income and substantially offsets the income statement impact of the excluded components. Also excludes the accrual of interest on interest rate swaps and the related hedged items. (c)Primarily consists of hedges of the foreign currency risk of long-term debt and AFS securities for changes in spot foreign currency rates. Gains and losses related to the derivatives and the hedged items due to changes in foreign currency rates and the income statement impact of excluded components were recorded primarily in principal transactions revenue and net interest income. (d)Consists of overall fair value hedges of physical commodities inventories that are generally carried at the lower of cost or net realizable value (net realizable value approximates fair value). Gains and losses were recorded in principal transactions revenue. (e)The assessment of hedge effectiveness excludes certain components of the changes in fair values of the derivatives and hedged items such as forward points on foreign exchange forward contracts, time values and cross-currency basis spreads. Excluded components may impact earnings either through amortization of the initial amount over the life of the derivative, or through fair value changes recognized in the current period. (f)Represents the change in value of amounts excluded from the assessment of effectiveness under the amortization approach, predominantly cross-currency basis spreads. The amount excluded at inception of the hedge is recognized in earnings over the life of the derivative. As of September 30, 2021 and December 31, 2020, the following amounts were recorded on the Consolidated balance sheets related to certain cumulative fair value hedge basis adjustments that are expected to reverse through the income statement in future periods as an adjustment to yield. Carrying amount of the hedged items(a)(b) Cumulative amount of fair value hedging adjustments included in the carrying amount of hedged items: September 30, 2021 (in millions) Active hedging relationships Discontinued hedging relationships(d)(e) Total Assets Investment securities - AFS $ 71,464 (c) $ 906 $ 558 $ 1,464 Liabilities Long-term debt $ 191,783 $ (1,121) $ 9,042 $ 7,921 Beneficial interests issued by consolidated VIEs 748 — (2) (2) Carrying amount of the hedged items(a)(b) Cumulative amount of fair value hedging adjustments included in the carrying amount of hedged items: December 31, 2020 (in millions) Active hedging relationships Discontinued hedging relationships(d)(e) Total Assets Investment securities - AFS $ 139,684 (c) $ 3,572 $ 847 $ 4,419 Liabilities Long-term debt $ 177,611 $ 3,194 $ 11,473 $ 14,667 Beneficial interests issued by consolidated VIEs 746 — (3) (3) (a)Excludes physical commodities with a carrying value of $19.3 billion and $11.5 billion at September 30, 2021 and December 31, 2020, respectively, to which the Firm applies fair value hedge accounting. As a result of the application of hedge accounting, these inventories are carried at fair value, thus recognizing unrealized gains and losses in current periods. Since the Firm exits these positions at fair value, there is no incremental impact to net income in future periods. (b)Excludes hedged items where only foreign currency risk is the designated hedged risk, as basis adjustments related to foreign currency hedges will not reverse through the income statement in future periods. At September 30, 2021 and December 31, 2020, the carrying amount excluded for AFS securities is $12.6 billion and $14.5 billion, respectively, and for long-term debt is $11.8 billion and $6.6 billion, respectively. (c)Carrying amount represents the amortized cost, net of allowance if applicable. Refer to Note 9 for additional information. (d)Represents basis adjustments existing on the balance sheet date associated with hedged items that have been de-designated from qualifying fair value hedging relationships. (e)Positive amounts related to assets represent cumulative fair value hedge basis adjustments that will reduce net interest income in future periods. Positive (negative) amounts related to liabilities represent cumulative fair value hedge basis adjustments that will increase (reduce) net interest income in future periods. Cash flow hedge gains and losses The following tables present derivative instruments, by contract type, used in cash flow hedge accounting relationships, and the pre-tax gains/(losses) recorded on such derivatives, for the three and nine months ended September 30, 2021 and 2020, respectively. The Firm includes the gains/(losses) on the hedging derivative in the same line item in the Consolidated statements of income as the change in cash flows on the related hedged item.

Gains and losses were recorded in net interest income. (b)Primarily consists of hedges of the foreign currency risk of non-U.S. dollar-denominated revenue and expense. The income statement classification of gains and losses follows the hedged item – primarily noninterest revenue and compensation expense. The Firm did not experience any forecasted transactions that failed to occur for the three and nine months ended September 30, 2021 and 2020. Over the next 12 months, the Firm expects that approximately $812 million (after-tax) of net gains recorded in AOCI at September 30, 2021, related to cash flow hedges will be recognized in income. For cash flow hedges that have been terminated, the maximum length of time over which the derivative results recorded in AOCI will be recognized in earnings is approximately eight years, corresponding to the timing of the originally hedged forecasted cash flows. For open cash flow hedges, the maximum length of time over which forecasted transactions are hedged is approximately seven years. The Firm’s longer-dated forecasted transactions relate to core lending and borrowing activities. Net investment hedge gains and losses The following table presents hedging instruments, by contract type, that were used in net investment hedge accounting relationships, and the pre-tax gains/(losses) recorded on such instruments for the three and nine months ended September 30, 2021 and 2020.

The Firm elects to record changes in fair value of these amounts directly in other income. (b)Excludes amounts reclassified from AOCI to income on the sale or liquidation of hedged entities. The amount reclassified for the three and nine months ended September 30, 2021 was not material. During the nine months ended September 30, 2020, the Firm reclassified pre-tax losses of $8 million to other income related to the liquidation of certain legal entities and the amount was not material for the three months ended September 30, 2020. Refer to Note 19 for further information. Gains and losses on derivatives used for specified risk management purposes The following table presents pre-tax gains/(losses) recorded on a limited number of derivatives, not designated in hedge accounting relationships, that are used to manage risks associated with certain specified assets and liabilities, including certain risks arising from mortgage commitments, warehouse loans, MSRs, wholesale lending exposures, and foreign currency-denominated assets and liabilities.

These derivatives do not include credit derivatives used to mitigate counterparty credit risk arising from derivative receivables, which is included in gains and losses on derivatives related to market-making activities and other derivatives. Gains and losses were recorded in principal transactions revenue. (c)Primarily relates to derivatives used to mitigate foreign exchange risk of specified foreign currency-denominated assets and liabilities. Gains and losses were recorded in principal transactions revenue. Gains and losses on derivatives related to market-making activities and other derivativesThe Firm makes markets in derivatives in order to meet the needs of customers and uses derivatives to manage certain risks associated with net open risk positions from its market-making activities, including the counterparty credit risk arising from derivative receivables. All derivatives not included in the hedge accounting or specified risk management categories above are included in this category. Gains and losses on these derivatives are primarily recorded in principal transactions revenue. Refer to Note 5 for information on principal transactions revenue. Credit derivatives Refer to Note 5 of JPMorgan Chase’s 2020 Form 10-K for a more detailed discussion of credit derivatives. The following tables present a summary of the notional amounts of credit derivatives and credit-related notes the Firm sold and purchased as of September 30, 2021 and December 31, 2020. The Firm does not use notional amounts of credit derivatives as the primary measure of risk management for such derivatives, because the notional amount does not take into account the probability of the occurrence of a credit event, the recovery value of the reference obligation, or related cash instruments and economic hedges, each of which reduces, in the Firm’s view, the risks associated with such derivatives.

437,627 (a)At September 30, 2021, and December 31, 2020, included total U.S. GSE obligations of $68.6 billion and $117.6 billion, respectively, which were mortgage-related. (b)Physical commodities inventories are generally accounted for at the lower of cost or net realizable value. “Net realizable value” is a term defined in U.S. GAAP as not exceeding fair value less costs to sell (“transaction costs”). Transaction costs for the Firm’s physical commodities inventories are either not applicable or immaterial to the value of the inventory. Therefore, net realizable value approximates fair value for the Firm’s physical commodities inventories. When fair value hedging has been applied (or when net realizable value is below cost), the carrying value of physical commodities approximates fair value, because under fair value hedge accounting, the cost basis is adjusted for changes in fair value. Refer to Note 4 for a further discussion of the Firm’s hedge accounting relationships. To provide consistent fair value disclosure information, all physical commodities inventories have been included in each period presented. (c)Balances reflect the reduction of securities owned (long positions) by the amount of identical securities sold but not yet purchased (short positions). (d)Certain investments that are measured at fair value using the net asset value per share (or its equivalent) as a practical expedient are not required to be classified in the fair value hierarchy. At September 30, 2021, and December 31, 2020, the fair values of these investments, which include certain hedge funds, private equity funds, real estate and other funds, were $813 million and $670 million, respectively. Included in these balances at September 30, 2021, and December 31, 2020, were trading assets of $56 million and $52 million, respectively, and other assets of $757 million and $618 million, respectively. (e)At September 30, 2021, and December 31, 2020, included $27.2 billion and $15.1 billion, respectively, of residential first-lien mortgages, and $8.1 billion and $6.3 billion, respectively, of commercial first-lien mortgages. Residential mortgage loans include conforming mortgage loans originated with the intent to sell to U.S. GSEs and government agencies of $13.1 billion and $8.4 billion, respectively. (f)As permitted under U.S. GAAP, the Firm has elected to net derivative receivables and derivative payables and the related cash collateral received and paid when a legally enforceable master netting agreement exists. The level 3 balances would be reduced if netting were applied, including the netting benefit associated with cash collateral. (g)Prior-period amounts have been revised to conform with the current presentation. Level 3 valuations Refer to Note 2 of JPMorgan Chase’s 2020 Form 10-K for further information on the Firm’s valuation process and a detailed discussion of the determination of fair value for individual financial instruments. The following table presents the Firm’s primary level 3 financial instruments, the valuation techniques used to measure the fair value of those financial instruments, the significant unobservable inputs, the range of values for those inputs and the weighted or arithmetic averages of such inputs. While the determination to classify an instrument within level 3 is based on the significance of the unobservable inputs to the overall fair value measurement, level 3 financial instruments typically include observable components (that is, components that are actively quoted and can be validated to external sources) in addition to the unobservable components. The level 1 and/or level 2 inputs are not included in the table. In addition, the Firm manages the risk of the observable components of level 3 financial instruments using securities and derivative positions that are classified within levels 1 or 2 of the fair value hierarchy. The range of values presented in the table is representative of the highest and lowest level input used to value the significant groups of instruments within a product/instrument classification. Where provided, the weighted averages of the input values presented in the table are calculated based on the fair value of the instruments that the input is being used to value. In the Firm’s view, the input range, weighted and arithmetic average values do not reflect the degree of input uncertainty or an assessment of the reasonableness of the Firm’s estimates and assumptions. Rather, they reflect the characteristics of the various instruments held by the Firm and the relative distribution of instruments within the range of characteristics. For example, two option contracts may have similar levels of market risk exposure and valuation uncertainty, but may have significantly different implied volatility levels because the option contracts have different underlyings, tenors, or strike prices. The input range and weighted average values will therefore vary from period-to-period and parameter-to-parameter based on the characteristics of the instruments held by the Firm at each balance sheet date.

Furthermore, the inputs presented for each valuation technique in the table are, in some cases, not applicable to every instrument valued using the technique as the characteristics of the instruments can differ. (b)Comprises U.S. GSE and government agency securities of $299 million, nonagency securities of $24 million and non-trading loans of $838 million. (c)Comprises nonagency securities of $19 million, trading loans of $41 million and non-trading loans of $420 million. (d)Comprises trading loans of $941 million and non-trading loans of $813 million. (e)Long-term debt, short-term borrowings and deposits include structured notes issued by the Firm that are financial instruments that typically contain embedded derivatives. The estimation of the fair value of structured notes includes the derivative features embedded within the instrument. The significant unobservable inputs are broadly consistent with those presented for derivative receivables. (f)Includes equity securities of $1.0 billion including $379 million in Other Assets, for which quoted prices are not readily available and the fair value is generally based on internal valuation techniques such as EBITDA multiples and comparable analysis. All other level 3 assets and liabilities are insignificant both individually and in aggregate. (g)Price is a significant unobservable input for certain instruments. When quoted market prices are not readily available, reliance is generally placed on price-based internal valuation techniques. The price input is expressed assuming a par value of $100. (h)Forward equity price is expressed as a percentage of the current equity price. (i)Amounts represent weighted averages except for derivative related inputs where arithmetic averages are used. Changes in and ranges of unobservable inputs Refer to Note 2 of JPMorgan Chase’s 2020 Form 10-K for a discussion of the impact on fair value of changes in unobservable inputs and the relationships between unobservable inputs as well as a description of attributes of the underlying instruments and external market factors that affect the range of inputs used in the valuation of the Firm’s positions. Changes in level 3 recurring fair value measurements The following tables include a rollforward of the Consolidated balance sheets amounts (including changes in fair value) for financial instruments classified by the Firm within level 3 of the fair value hierarchy for the three and nine months ended September 30, 2021 and 2020. When a determination is made to classify a financial instrument within level 3, the determination is based on the significance of the unobservable inputs to the overall fair value measurement. However, level 3 financial instruments typically include, in addition to the unobservable or level 3 components, observable components (that is, components that are actively quoted and can be validated to external sources); accordingly, the gains and losses in the table below include changes in fair value due in part to observable factors that are part of the valuation methodology. Also, the Firm risk-manages the observable components of level 3 financial instruments using securities and derivative positions that are classified within level 1 or 2 of the fair value hierarchy; as these level 1 and level 2 risk management instruments are not included below, the gains or losses in the following tables do not reflect the effect of the Firm’s risk management activities related to such level 3 instruments.

Level 3 analysis Consolidated balance sheets changes The following describes significant changes to level 3 assets since December 31, 2020, for those items measured at fair value on a recurring basis. Refer to Assets and liabilities measured at fair value on a nonrecurring basis on page 109 for further information on changes impacting items measured at fair value on a nonrecurring basis. Three and nine months ended September 30, 2021 Level 3 assets were $17.1 billion at September 30, 2021, reflecting an increase of $1.2 billion from June 30, 2021 and an increase of $697 million from December 31, 2020. The increase for the three months ended September 30, 2021 was largely driven by an $802 million increase in MSRs. The increase for the nine months ended September 30, 2021 was predominantly driven by: •a $2.1 billion increase in MSRs. partially offset by •$444 million decrease in gross interest rate derivative receivables due to settlements net of gains and $443 million decrease in gross equity derivative receivables due to settlements and transfers net of gains. Refer to Note 14 for information on MSRs. Refer to the sections below for additional information. Transfers between levels for instruments carried at fair value on a recurring basis For the three months ended September 30, 2021, there were no significant transfers from level 2 into level 3. For the nine months ended September 30, 2021, significant transfers from level 2 into level 3 included the following: •$882 million of total debt and equity instruments, largely trading loans, driven by a decrease in observability. •$937 million of gross equity derivative receivables and $704 million of gross equity derivative payables as a result of a decrease in observability and an increase in the significance of unobservable inputs. •$1.0 billion of non-trading loans driven by a decrease in observability. For the three months ended September 30, 2021, there were no significant transfers from level 3 into level 2. For the nine months ended September 30, 2021, significant transfers from level 3 into level 2 included the following: •$1.1 billion of total debt and equity instruments, largely trading loans, driven by an increase in observability. •$1.7 billion of gross equity derivative receivables and $1.6 billion of gross equity derivative payables as a result of an increase in observability and a decrease in the significance of unobservable inputs. •$673 million of non-trading loans, driven by an increase in observability. •$736 million of long-term debt driven, by an increase in observability and a decrease in the significance of unobservable inputs for certain structured notes. For the three months ended September 30, 2020, there were no significant transfers from level 2 into level 3. For the nine months ended September 30, 2020, significant transfers from level 2 into level 3 included the following: •$2.2 billion of gross equity derivative receivables and $2.7 billion of gross equity derivative payables as a result of a decrease in observability and an increase in the significance of unobservable inputs. •$2.3 billion of non-trading loans, driven by a decrease in observability. •$1.1 billion of long-term debt, driven by a decrease in observability and an increase in the significance of unobservable inputs for certain structured notes. For the three months ended September 30, 2020, significant transfers from level 3 into level 2 included the following: •$965 million of gross equity derivative payables as a result of an increase in observability and a decrease in the significance of unobservable inputs. For the nine months ended September 30, 2020, significant transfers from level 3 into level 2 included the following: •$1.7 billion of gross equity derivative receivables and $1.9 billion of gross equity derivative payables as a result of an increase in observability and a decrease in the significance of unobservable inputs. •$1.1 billion of long-term debt driven by an increase in observability and a decrease in the significance of unobservable inputs for certain structured notes. All transfers are based on changes in the observability and/or significance of the valuation inputs and are assumed to occur at the beginning of the quarterly reporting period in which they occur. Gains and losses The following describes significant components of total realized/unrealized gains/(losses) for instruments measured at fair value on a recurring basis for the periods indicated. These amounts exclude any effects of the Firm’s risk management activities where the financial instruments are classified as level 1 and 2 of the fair value hierarchy. Refer to Changes in level 3 recurring fair value measurements rollforward tables on pages 102-108 for further information on these instruments. Three months ended September 30, 2021 •$1.3 billion of net gains on assets, driven by gains in net interest rate derivative receivables and net equity derivative receivables due to market movements. •$928 million of net gains on liabilities, largely driven by gains in short-term borrowings due to market movements. Three months ended September 30, 2020 •$744 million of net losses on assets, driven by market movements in net equity derivative receivables. •$763 million of net losses on liabilities, driven by market movements in long-term debt. Nine months ended September 30, 2021 •$1.0 billion of net gains on assets, driven by gains in net interest rate derivative receivables due to market movements, partially offset by losses in net commodity derivative receivables due to market movements. •$988 million of net gains on liabilities, driven by gains in short-term borrowings due to market movements. Nine months ended September 30, 2020 •$374 million of net gains on assets, driven by gains in net interest rate derivative receivables due to market movements largely offset by losses in MSRs reflecting faster prepayment speeds on lower rates. Refer to Note 14 for additional information on MSRs. •$845 million of net gains on liabilities, predominantly driven by market movements in long-term debt. Credit and funding adjustments — derivatives The following table provides the impact of credit and funding adjustments on principal transactions revenue in the respective periods, excluding the effect of any associated hedging activities.

Assets and liabilities measured at fair value on a nonrecurring basis The following tables present the assets and liabilities held as of September 30, 2021 and 2020, for which nonrecurring fair value adjustments were recorded during the nine months ended September 30, 2021 and 2020, by major product category and fair value hierarchy.

Of the $1.2 billion in level 3 assets measured at fair value on a nonrecurring basis as of September 30, 2021, $1.1 billion related to equity securities adjusted based on the measurement alternative. These equity securities are classified as level 3 due to the infrequency of the observable prices and/or the restrictions on the shares. (b)Of the $314 million in level 3 assets measured at fair value on a nonrecurring basis as of September 30, 2021, $208 million related to residential real estate loans carried at the net realizable value of the underlying collateral (e.g., collateral-dependent loans). These amounts are classified as level 3 as they are valued using information from broker’s price opinions, appraisals and automated valuation models and discounted based upon the Firm’s experience with actual liquidation values. These discounts ranged from 12% to 45% with a weighted average of 25%. Nonrecurring fair value changes The following table presents the total change in value of assets and liabilities for which fair value adjustments have been recognized for the three and nine months ended September 30, 2021 and 2020, related to assets and liabilities held at those dates.

Refer to Note 11 for further information about the measurement of collateral-dependent loans. Equity securities without readily determinable fair values The Firm measures certain equity securities without readily determinable fair values at cost less impairment (if any), plus or minus observable price changes from an identical or similar investment of the same issuer, with such changes recognized in other income. In its determination of the new carrying values upon observable price changes, the Firm may adjust the prices if deemed necessary to arrive at the Firm’s estimated fair values. Such adjustments may include adjustments to reflect the different rights and obligations of similar securities, and other adjustments that are consistent with the Firm’s valuation techniques for private equity direct investments. The following table presents the carrying value of equity securities without readily determinable fair values held as of September 30, 2021 and 2020, that are measured under the measurement alternative and the related adjustments recorded during the periods presented for those securities with observable price changes. These securities are included in the nonrecurring fair value tables when applicable price changes are observable.

The period-end carrying values reflect cumulative purchases and sales in addition to upward and downward carrying value changes. (b)The cumulative upward carrying value changes between January 1, 2018 and September 30, 2021 were $826 million. (c)The cumulative downward carrying value changes/impairment between January 1, 2018 and September 30, 2021 were $(335) million. Included in other assets above is the Firm’s interest in approximately 40 million Visa Class B common shares, recorded at a nominal carrying value. These shares are subject to certain transfer restrictions currently and will be convertible into Visa Class A common shares upon final resolution of certain litigation matters involving Visa. The conversion rate of Visa Class B common shares into Visa Class A common shares is 1.6228 at September 30, 2021, and may be adjusted by Visa depending on developments related to the litigation matters. Additional disclosures about the fair value of financial instruments that are not carried on the Consolidated balance sheets at fair value The following table presents, by fair value hierarchy classification, the carrying values and estimated fair values at September 30, 2021, and December 31, 2020, of financial assets and liabilities, excluding financial instruments that are carried at fair value on a recurring basis, and their classification within the fair value hierarchy.

For certain loans, the fair value is measured based on the value of the underlying collateral. Carrying value of the loan takes into account the loan’s allowance for loan losses, which represents the loan’s expected credit losses over its remaining expected life. The difference between the estimated fair value and carrying value of a loan is generally attributable to changes in market interest rates, including credit spreads, market liquidity premiums and other factors that affect the fair value of a loan but do not affect its carrying value. The majority of the Firm’s lending-related commitments are not carried at fair value on a recurring basis on the Consolidated balance sheets. The carrying value and the estimated fair value of these wholesale lending-related commitments were as follows for the periods indicated.

(b)Includes the wholesale allowance for lending-related commitments. The Firm does not estimate the fair value of consumer off-balance sheet lending-related commitments. In many cases, the Firm can reduce or cancel these commitments by providing the borrower notice or, in some cases as permitted by law, without notice.

(b)Physical commodities inventories are generally accounted for at the lower of cost or net realizable value. “Net realizable value” is a term defined in U.S. GAAP as not exceeding fair value less costs to sell (“transaction costs”). Transaction costs for the Firm’s physical commodities inventories are either not applicable or immaterial to the value of the inventory. Therefore, net realizable value approximates fair value for the Firm’s physical commodities inventories. When fair value hedging has been applied (or when net realizable value is below cost), the carrying value of physical commodities approximates fair value, because under fair value hedge accounting, the cost basis is adjusted for changes in fair value. Refer to Note 4 for a further discussion of the Firm’s hedge accounting relationships. To provide consistent fair value disclosure information, all physical commodities inventories have been included in each period presented.

Level 3 valuations Level 3 valuations Refer to Note 2 of JPMorgan Chase’s 2020 Form 10-K for further information on the Firm’s valuation process and a detailed discussion of the determination of fair value for individual financial instruments. The following table presents the Firm’s primary level 3 financial instruments, the valuation techniques used to measure the fair value of those financial instruments, the significant unobservable inputs, the range of values for those inputs and the weighted or arithmetic averages of such inputs. While the determination to classify an instrument within level 3 is based on the significance of the unobservable inputs to the overall fair value measurement, level 3 financial instruments typically include observable components (that is, components that are actively quoted and can be validated to external sources) in addition to the unobservable components. The level 1 and/or level 2 inputs are not included in the table. In addition, the Firm manages the risk of the observable components of level 3 financial instruments using securities and derivative positions that are classified within levels 1 or 2 of the fair value hierarchy. The range of values presented in the table is representative of the highest and lowest level input used to value the significant groups of instruments within a product/instrument classification. Where provided, the weighted averages of the input values presented in the table are calculated based on the fair value of the instruments that the input is being used to value. In the Firm’s view, the input range, weighted and arithmetic average values do not reflect the degree of input uncertainty or an assessment of the reasonableness of the Firm’s estimates and assumptions. Rather, they reflect the characteristics of the various instruments held by the Firm and the relative distribution of instruments within the range of characteristics. For example, two option contracts may have similar levels of market risk exposure and valuation uncertainty, but may have significantly different implied volatility levels because the option contracts have different underlyings, tenors, or strike prices. The input range and weighted average values will therefore vary from period-to-period and parameter-to-parameter based on the characteristics of the instruments held by the Firm at each balance sheet date.

(i) Amounts represent weighted averages except for derivative related inputs where arithmetic averages are used. Changes in and ranges of unobservable inputs Changes in and ranges of unobservable inputs Refer to Note 2 of JPMorgan Chase’s 2020 Form 10-K for a discussion of the impact on fair value of changes in unobservable inputs and the relationships between unobservable inputs as well as a description of attributes of the underlying instruments and external market factors that affect the range of inputs used in the valuation of the Firm’s positions. Refer to Note 2 of JPMorgan Chase’s 2020 Form 10-K for a discussion of the impact on fair value of changes in unobservable inputs and the relationships between unobservable inputs as well as a description of attributes of the underlying instruments and external market factors that affect the range of inputs used in the valuation of the Firm’s positions. Changes in level 3 recurring fair value measurements Changes in level 3 recurring fair value measurements The following tables include a rollforward of the Consolidated balance sheets amounts (including changes in fair value) for financial instruments classified by the Firm within level 3 of the fair value hierarchy for the three and nine months ended September 30, 2021 and 2020. When a determination is made to classify a financial instrument within level 3, the determination is based on the significance of the unobservable inputs to the overall fair value measurement. However, level 3 financial instruments typically include, in addition to the unobservable or level 3 components, observable components (that is, components that are actively quoted and can be validated to external sources); accordingly, the gains and losses in the table below include changes in fair value due in part to observable factors that are part of the valuation methodology. Also, the Firm risk-manages the observable components of level 3 financial instruments using securities and derivative positions that are classified within level 1 or 2 of the fair value hierarchy; as these level 1 and level 2 risk management instruments are not included below, the gains or losses in the following tables do not reflect the effect of the Firm’s risk management activities related to such level 3 instruments.

    Securities Financing Transactions Disclosures [Abstract]                                                            
        Schedule of securities sold under repurchase agreements, netting & securities loaned                            | The table below summarizes the gross and net amounts of the Firm’s securities financing agreements as of September 30, 2021 and December 31, 2020. When the Firm has obtained an appropriate legal opinion with respect to a master netting agreement with a counterparty and where other relevant netting criteria under U.S. GAAP are met, the Firm nets, on the Consolidated balance sheets, the balances outstanding under its securities financing agreements with the same counterparty. In addition, the Firm exchanges securities and/or cash collateral with its counterparty to reduce the economic exposure with the counterparty, but such collateral is not eligible for net Consolidated balance sheet presentation. Where the Firm has obtained an appropriate legal opinion with respect to the counterparty master netting agreement, such collateral, along with securities financing balances that do not meet all these relevant netting criteria under U.S. GAAP, is presented in the table below as “Amounts not nettable on the Consolidated balance sheets,” and reduces the “Net amounts” presented. Where a legal opinion has not been either sought or obtained, the securities financing balances are presented gross in the “Net amounts” below. In transactions where the Firm is acting as the lender in a securities-for-securities lending agreement and receives securities that can be pledged or sold as collateral, the Firm recognizes the securities received at fair value within other assets and the obligation to return those securities within accounts payable and other liabilities on the Consolidated balance sheets.

(b)In some cases, collateral exchanged with a counterparty exceeds the net asset or liability balance with that counterparty. In such cases, the amounts reported in this column are limited to the related net asset or liability with that counterparty.

    Litigation [Abstract]                                                                                               
        Litigation                                                                                                      | Litigation Contingencies As of September 30, 2021, the Firm and its subsidiaries and affiliates are defendants or respondents in numerous legal proceedings, including private, civil litigations, government investigations or regulatory enforcement matters. The litigations range from individual actions involving a single plaintiff to class action lawsuits with potentially millions of class members. Investigations and regulatory enforcement matters involve both formal and informal proceedings, by both governmental agencies and self-regulatory organizations. These legal proceedings are at varying stages of adjudication, arbitration or investigation, and involve each of the Firm’s lines of business and several geographies and a wide variety of claims (including common law tort and contract claims and statutory antitrust, securities and consumer protection claims), some of which present novel legal theories. The Firm believes the estimate of the aggregate range of reasonably possible losses, in excess of reserves established, for its legal proceedings is from $0 to approximately $1.5 billion at September 30, 2021. This estimated aggregate range of reasonably possible losses was based upon information available as of that date for those proceedings in which the Firm believes that an estimate of reasonably possible loss can be made. For certain matters, the Firm does not believe that such an estimate can be made, as of that date. The Firm’s estimate of the aggregate range of reasonably possible losses involves significant judgment, given: •the number, variety and varying stages of the proceedings, including the fact that many are in preliminary stages, •the existence in many such proceedings of multiple defendants, including the Firm, whose share of liability (if any) has yet to be determined, •the numerous yet-unresolved issues in many of the proceedings, including issues regarding class certification and the scope of many of the claims, and •the attendant uncertainty of the various potential outcomes of such proceedings, including where the Firm has made assumptions concerning future rulings by the court or other adjudicator, or about the behavior or incentives of adverse parties or regulatory authorities, and those assumptions prove to be incorrect. In addition, the outcome of a particular proceeding may be a result which the Firm did not take into account in its estimate because the Firm had deemed the likelihood of that outcome to be remote. Accordingly, the Firm’s estimate of the aggregate range of reasonably possible losses will change from time to time, and actual losses may vary significantly. Set forth below are descriptions of the Firm’s material legal proceedings. Amrapali. India’s Enforcement Directorate (“ED”) is investigating J.P. Morgan India Private Limited in connection with investments made in 2010 and 2012 by two offshore funds formerly managed by JPMorgan Chase entities into residential housing projects developed by the Amrapali Group (“Amrapali”). In 2017, numerous creditors filed civil claims against Amrapali including petitions brought by home buyers relating to delays in delivering or failure to deliver residential units. The home buyers’ petitions have been overseen by the Supreme Court of India and is ongoing. In August 2021, the ED issued an order fining J.P. Morgan India Private Limited approximately $31.5 million. The Firm is appealing the order and the fine. Relatedly, in July 2019, the Supreme Court of India issued an order making preliminary findings that Amrapali and other parties, including unspecified JPMorgan Chase entities and the offshore funds that had invested in the projects, violated certain currency control and money laundering provisions, and ordering the ED to conduct a further inquiry under India’s Prevention of Money Laundering Act (“PMLA”) and Foreign Exchange Management Act (“FEMA”). In May 2020, the ED attached approximately $25 million from J.P. Morgan India Private Limited in connection with the criminal PMLA investigation. The Firm is responding to and cooperating with the PMLA investigation. Federal Republic of Nigeria Litigation. JPMorgan Chase Bank, N.A. operated an escrow and depository account for the Federal Government of Nigeria (“FGN”) and two major international oil companies. The account held approximately $1.1 billion in connection with a dispute among the clients over rights to an oil field. Following the settlement of the dispute, JPMorgan Chase Bank, N.A. paid out the monies in the account in 2011 and 2013 in accordance with directions received from its clients. In November 2017, the Federal Republic of Nigeria (“FRN”) commenced a claim in the English High Court for approximately $875 million in payments made out of the accounts. The FRN, claiming to be the same entity as the FGN, alleges that the payments were instructed as part of a complex fraud not involving JPMorgan Chase Bank, N.A., but that JPMorgan Chase Bank, N.A. was or should have been on notice that the payments may be fraudulent. JPMorgan Chase Bank, N.A. applied for summary judgment and was unsuccessful. The claim is ongoing and a trial has been scheduled to commence in February 2022. Foreign Exchange Investigations and Litigation. The Firm previously reported settlements with certain government authorities relating to its foreign exchange (“FX”) sales and trading activities and controls related to those activities. Among those resolutions, in May 2015, the Firm pleaded guilty to a single violation of federal antitrust law. In January 2017, the Firm was sentenced, with judgment entered thereafter and a term of probation which ended in January 2020, with the Firm remaining in good standing throughout the probation period. The Department of Labor granted the Firm a five-year exemption of disqualification that allows the Firm and its affiliates to continue to rely on the Qualified Professional Asset Manager exemption under the Employee Retirement Income Security Act (“ERISA”) until January 2023. The Firm will need the Department of Labor to approve a further exemption to cover the remainder of the ten-year disqualification period. A South Africa Competition Commission matter is the remaining FX-related governmental inquiry, and is currently pending before the South Africa Competition Tribunal. In August 2018, the United States District Court for the Southern District of New York granted final approval to the Firm’s settlement of a consolidated class action brought by U.S.-based plaintiffs, which principally alleged violations of federal antitrust laws based on an alleged conspiracy to manipulate foreign exchange rates and also sought damages on behalf of persons who transacted in FX futures and options on futures. Certain members of the settlement class filed requests to the Court to be excluded from the class, and certain of them filed a complaint against the Firm and other foreign exchange dealers in November 2018. A number of these actions remain pending. Further, a putative class action has been filed against the Firm and other foreign exchange dealers on behalf of certain consumers who purchased foreign currencies at allegedly inflated rates. Another putative class action was brought against the Firm and other foreign exchange dealers on behalf of purported indirect purchasers of FX instruments. In 2020, the Court approved a settlement by the Firm and 11 other defendants of that class action for a total of $10 million. In addition, some FX-related individual and putative class actions based on similar alleged underlying conduct have been filed outside the U.S., including in the U.K., Israel, Brazil and Australia. Inquiries Concerning Preservation Requirements. The Firm has been responding to requests for information and other material from certain of its regulators concerning its compliance with records preservation requirements in connection with business communications sent over electronic messaging channels that have not been approved by the Firm. The Firm is cooperating with these inquiries and is currently engaged in certain advanced resolution discussions. There is no assurance that the discussions will result in a resolution. Interchange Litigation. Groups of merchants and retail associations filed a series of class action complaints alleging that Visa and Mastercard, as well as certain banks, conspired to set the price of credit and debit card interchange fees and enacted related rules in violation of antitrust laws. In 2012, the parties initially settled the cases for a cash payment, a temporary reduction of credit card interchange, and modifications to certain credit card network rules. In 2017, after the approval of that settlement was reversed on appeal, the case was remanded to the United States District Court for the Eastern District of New York for further proceedings consistent with the appellate decision. The original class action was divided into two separate actions, one seeking primarily monetary relief and the other seeking primarily injunctive relief. In September 2018, the parties to the class action seeking monetary relief finalized an agreement which amends and supersedes the prior settlement agreement. Pursuant to this settlement, the defendants collectively contributed an additional $900 million to the approximately $5.3 billion previously held in escrow from the original settlement. In December 2019, the amended agreement was approved by the District Court. Certain merchants appealed the District Court’s approval order, and those appeals are pending. Based on the percentage of merchants that opted out of the amended class settlement, $700 million has been returned to the defendants from the settlement escrow in accordance with the settlement agreement. The class action seeking primarily injunctive relief continues separately, and in September 2021, the District Court granted plaintiffs’ motion for class certification in part, and denied the motion in part. In addition, certain merchants have filed individual actions raising similar allegations against Visa and Mastercard, as well as against the Firm and other banks, and some of those actions remain pending. LIBOR and Other Benchmark Rate Investigations and Litigation. JPMorgan Chase has responded to inquiries from various governmental agencies and entities around the world relating primarily to the British Bankers Association’s ("BBA") London Interbank Offered Rate (“LIBOR”) for various currencies and the European Banking Federation’s Euro Interbank Offered Rate (“EURIBOR”). The Swiss Competition Commission’s investigation relating to EURIBOR, to which the Firm and other banks are subject, continues. In December 2016, the European Commission issued a decision against the Firm and other banks finding an infringement of European antitrust rules relating to EURIBOR. The Firm has filed an appeal of that decision with the European General Court, and that appeal is pending. In addition, the Firm has been named as a defendant along with other banks in various individual and putative class actions related to benchmark rates, including U.S. dollar LIBOR. In actions related to U.S. dollar LIBOR during the period that it was administered by the BBA, the Firm has obtained dismissal of certain actions and resolved certain other actions, and others are in various stages of litigation. The United States District Court for the Southern District of New York has granted class certification of antitrust claims related to bonds and interest rate swaps sold directly by the defendants, including the Firm. In a consolidated putative class action related to the period that U.S. dollar LIBOR was administered by ICE Benchmark Administration, the District Court granted the motion by defendants, including the Firm, to dismiss plaintiffs’ complaint, and the plaintiffs have appealed. In addition, in August 2020, a group of individual plaintiffs filed a lawsuit asserting antitrust claims, alleging that the Firm and other defendants were engaged in an unlawful agreement to set U.S. dollar LIBOR and conspired to monopolize the market for LIBOR-based consumer loans and credit cards. In November 2020 and May 2021, plaintiffs filed motions for a preliminary injunction each seeking to enjoin defendants from setting U.S. dollar LIBOR and to prohibit defendants from enforcing any financial instruments that rely on U.S. dollar LIBOR. The court held a hearing to address these motions in September 2021. The Firm’s settlements of putative class actions related to Swiss franc LIBOR, the Singapore Interbank Offered Rate and the Singapore Swap Offer Rate, and the Australian Bank Bill Swap Reference Rate remain subject to court approval. Metals and U.S. Treasuries Investigations and Litigation and Related Inquiries. The Firm previously reported that it and/or certain of its subsidiaries had entered into resolutions with the U.S. Department of Justice (“DOJ”), the U.S. Commodity Futures Trading Commission (“CFTC”) and the U.S. Securities and Exchange Commission (“SEC”), which, collectively, resolved those agencies’ respective investigations relating to historical trading practices by former employees in the precious metals and U.S. treasuries markets and related conduct from 2008 to 2016. The Firm entered into a Deferred Prosecution Agreement (“DPA”) with the DOJ in which it agreed to the filing of a criminal information charging JPMorgan Chase & Co. with two counts of wire fraud and agreed, along with JPMorgan Chase Bank, N.A. and J.P. Morgan Securities LLC, to certain terms and obligations as set forth therein. Under the terms of the DPA, the criminal information will be dismissed after three years, provided that JPMorgan Chase & Co., JPMorgan Chase Bank, N.A. and J.P. Morgan Securities LLC fully comply with all of their obligations. Across the three resolutions with the DOJ, CFTC and SEC, JPMorgan Chase & Co., JPMorgan Chase Bank, N.A. and J.P. Morgan Securities LLC agreed to pay a total monetary amount of approximately $920 million. A portion of the total monetary amount includes victim compensation payments. Several putative class action complaints have been filed in the United States District Court for the Southern District of New York against the Firm and certain former employees, alleging a precious metals futures and options price manipulation scheme in violation of the Commodity Exchange Act. Some of the complaints also allege unjust enrichment and deceptive acts or practices under the General Business Law of the State of New York. The Court consolidated these putative class actions in February 2019, and the consolidated action is stayed through December 2021. In July 2021, the parties informed the Court that they have entered into a settlement to resolve the action. In Canada, plaintiffs have moved to commence putative class action proceedings based on similar alleged underlying conduct for precious metals. In addition, several putative class actions were filed in the United States District Courts for the Northern District of Illinois and Southern District of New York against the Firm, alleging manipulation of U.S. Treasury futures and options, and bringing claims under the Commodity Exchange Act. Some of the complaints also allege unjust enrichment. The actions in the Northern District of Illinois have been transferred to the Southern District of New York. The Court consolidated these putative class actions in October 2020 and plaintiffs filed their consolidated amended complaint in April 2021. In May 2021, the parties informed the Court that they have entered into a settlement to resolve the action. In October 2020, two putative class action complaints were filed under the Securities Exchange Act of 1934 in the United States District Court for the Eastern District of New York against the Firm and certain individual defendants on behalf of shareholders who acquired shares during the putative class period alleging that certain SEC filings of the Firm were materially false or misleading in that they did not disclose certain information relating to the above-referenced investigations. The Court consolidated these putative class actions in January 2021. Plaintiffs filed their second amended complaint in May 2021, which additionally alleged that certain orders in precious metals futures contracts placed by precious metals futures traders during the putative class period were materially false and misleading. Defendants have moved to dismiss. Securities Lending Antitrust Litigation. JPMorgan Chase Bank, N.A., J.P. Morgan Securities LLC, J.P. Morgan Prime, Inc., and J.P. Morgan Strategic Securities Lending Corp. are named as defendants in a putative class action filed in the United States District Court for the Southern District of New York. The complaint asserts violations of federal antitrust law and New York State common law in connection with an alleged conspiracy to prevent the emergence of anonymous exchange trading for securities lending transactions. Defendants’ motion to dismiss the complaint was denied. Plaintiffs have moved to certify a class in this action, which defendants are opposing. Wendel. Since 2012, the French criminal authorities have been investigating a series of transactions entered into by senior managers of Wendel Investissement (“Wendel”) during the period from 2004 through 2007 to restructure their shareholdings in Wendel. JPMorgan Chase Bank, N.A., Paris branch provided financing for the transactions to a number of managers of Wendel in 2007. JPMorgan Chase Bank, N.A. cooperated with the investigation. The investigating judges issued an ordonnance de renvoi in November 2016, referring JPMorgan Chase Bank, N.A. to the French tribunal correctionnel for alleged complicity in tax fraud. In January 2018, the Paris Court of Appeal issued a decision cancelling the mise en examen of JPMorgan Chase Bank, N.A. The Court of Cassation, France’s highest court, ruled in September 2018 that a mise en examen is a prerequisite for an ordonnance de renvoi and in January 2020 ordered the annulment of the ordonnance de renvoi referring JPMorgan Chase Bank, N.A. to the French tribunal correctionnel. The Court of Appeal found in January 2021 that it had no power to take further action against JPMorgan Chase Bank, N.A. following the Court of Cassation’s ruling. At the opening of a trial of the managers of Wendel in January 2021, the tribunal correctionnel directed the criminal authorities to clarify whether a further investigation should be opened against JPMorgan Chase Bank, N.A., pending which the trial was postponed. In April 2021, the Court of Cassation declined to hear JPMorgan Chase Bank, N.A.’s appeal of the January 2021 decision of the tribunal correctionnel at this stage of the proceedings. In August 2021, JPMorgan Chase Bank, N.A. entered into a Convention Judicaire d’Intérêt Public with the French criminal authorities, under which it agreed to pay a fine of €25 million to resolve the potential legal proceedings. The resolution, which did not contain any admissions, was approved by the Presiding Judge of the tribunal judiciaire, and JPMorgan Chase Bank, N.A. paid the fine in September 2021. In addition, a number of the managers have commenced civil proceedings against JPMorgan Chase Bank, N.A. The claims are separate, involve different allegations and are at various stages of proceedings. * * * In addition to the various legal proceedings discussed above, JPMorgan Chase and its subsidiaries are named as defendants or are otherwise involved in a substantial number of other legal proceedings. The Firm believes it has meritorious defenses to the claims asserted against it in its currently outstanding legal proceedings and it intends to defend itself vigorously. Additional legal proceedings may be initiated from time to time in the future. The Firm has established reserves for several hundred of its currently outstanding legal proceedings. In accordance with the provisions of U.S. GAAP for contingencies, the Firm accrues for a litigation-related liability when it is probable that such a liability has been incurred and the amount of the loss can be reasonably estimated. The Firm evaluates its outstanding legal proceedings each quarter to assess its litigation reserves, and makes adjustments in such reserves, upward or downward, as appropriate, based on management’s best judgment after consultation with counsel. The Firm’s legal expense was $76 million and $524 million for the three months ended September 30, 2021 and 2020, respectively, and $289 million and $839 million for the nine months ended September 30, 2021 and 2020. There is no assurance that the Firm’s litigation reserves will not need to be adjusted in the future. In view of the inherent difficulty of predicting the outcome of legal proceedings, particularly where the claimants seek very large or indeterminate damages, or where the matters present novel legal theories, involve a large number of parties or are in early stages of discovery, the Firm cannot state with confidence what will be the eventual outcomes of the currently pending matters, the timing of their ultimate resolution or the eventual losses, fines, penalties or consequences related to those matters. JPMorgan Chase believes, based upon its current knowledge and after consultation with counsel, consideration of the material legal proceedings described above and after taking into account its current litigation reserves and its estimated aggregate range of possible losses, that the other legal proceedings currently pending against it should not have a material adverse effect on the Firm’s consolidated financial condition. The Firm notes, however, that in light of the uncertainties involved in such proceedings, there is no assurance that the ultimate resolution of these matters will not significantly exceed the reserves it has currently accrued or that a matter will not have material reputational consequences. As a result, the outcome of a particular matter may be material to JPMorgan Chase’s operating results for a particular period, depending on, among other factors, the size of the loss or liability imposed and the level of JPMorgan Chase’s income for that period. Contingencies Contingencies As of September 30, 2021, the Firm and its subsidiaries and affiliates are defendants or respondents in numerous legal proceedings, including private, civil litigations, government investigations or regulatory enforcement matters. The litigations range from individual actions involving a single plaintiff to class action lawsuits with potentially millions of class members. Investigations and regulatory enforcement matters involve both formal and informal proceedings, by both governmental agencies and self-regulatory organizations. These legal proceedings are at varying stages of adjudication, arbitration or investigation, and involve each of the Firm’s lines of business and several geographies and a wide variety of claims (including common law tort and contract claims and statutory antitrust, securities and consumer protection claims), some of which present novel legal theories. The Firm believes the estimate of the aggregate range of reasonably possible losses, in excess of reserves established, for its legal proceedings is from $0 to approximately $1.5 billion at September 30, 2021. This estimated aggregate range of reasonably possible losses was based upon information available as of that date for those proceedings in which the Firm believes that an estimate of reasonably possible loss can be made. For certain matters, the Firm does not believe that such an estimate can be made, as of that date. The Firm’s estimate of the aggregate range of reasonably possible losses involves significant judgment, given: •the number, variety and varying stages of the proceedings, including the fact that many are in preliminary stages, •the existence in many such proceedings of multiple defendants, including the Firm, whose share of liability (if any) has yet to be determined, •the numerous yet-unresolved issues in many of the proceedings, including issues regarding class certification and the scope of many of the claims, and •the attendant uncertainty of the various potential outcomes of such proceedings, including where the Firm has made assumptions concerning future rulings by the court or other adjudicator, or about the behavior or incentives of adverse parties or regulatory authorities, and those assumptions prove to be incorrect.

Accordingly, the Firm’s estimate of the aggregate range of reasonably possible losses will change from time to time, and actual losses may vary significantly. Set forth below are descriptions of the Firm’s material legal proceedings. Amrapali. India’s Enforcement Directorate (“ED”) is investigating J.P. Morgan India Private Limited in connection with investments made in 2010 and 2012 by two offshore funds formerly managed by JPMorgan Chase entities into residential housing projects developed by the Amrapali Group (“Amrapali”). In 2017, numerous creditors filed civil claims against Amrapali including petitions brought by home buyers relating to delays in delivering or failure to deliver residential units. The home buyers’ petitions have been overseen by the Supreme Court of India and is ongoing. In August 2021, the ED issued an order fining J.P. Morgan India Private Limited approximately $31.5 million. The Firm is appealing the order and the fine. Relatedly, in July 2019, the Supreme Court of India issued an order making preliminary findings that Amrapali and other parties, including unspecified JPMorgan Chase entities and the offshore funds that had invested in the projects, violated certain currency control and money laundering provisions, and ordering the ED to conduct a further inquiry under India’s Prevention of Money Laundering Act (“PMLA”) and Foreign Exchange Management Act (“FEMA”). In May 2020, the ED attached approximately $25 million from J.P. Morgan India Private Limited in connection with the criminal PMLA investigation. The Firm is responding to and cooperating with the PMLA investigation. Federal Republic of Nigeria Litigation. JPMorgan Chase Bank, N.A. operated an escrow and depository account for the Federal Government of Nigeria (“FGN”) and two major international oil companies. The account held approximately $1.1 billion in connection with a dispute among the clients over rights to an oil field. Following the settlement of the dispute, JPMorgan Chase Bank, N.A. paid out the monies in the account in 2011 and 2013 in accordance with directions received from its clients. In November 2017, the Federal Republic of Nigeria (“FRN”) commenced a claim in the English High Court for approximately $875 million in payments made out of the accounts. The FRN, claiming to be the same entity as the FGN, alleges that the payments were instructed as part of a complex fraud not involving JPMorgan Chase Bank, N.A., but that JPMorgan Chase Bank, N.A. was or should have been on notice that the payments may be fraudulent. JPMorgan Chase Bank, N.A. applied for summary judgment and was unsuccessful. The claim is ongoing and a trial has been scheduled to commence in February 2022. Foreign Exchange Investigations and Litigation. The Firm previously reported settlements with certain government authorities relating to its foreign exchange (“FX”) sales and trading activities and controls related to those activities. Among those resolutions, in May 2015, the Firm pleaded guilty to a single violation of federal antitrust law. In January 2017, the Firm was sentenced, with judgment As of September 30, 2021, the Firm and its subsidiaries and affiliates are defendants or respondents in numerous legal proceedings, including private, civil litigations, government investigations or regulatory enforcement matters.

This estimated aggregate range of reasonably possible losses was based upon information available as of that date for those proceedings in which the Firm believes that an estimate of reasonably possible loss can be made. For certain matters, the Firm does not believe that such an estimate can be made, as of that date. The Firm’s estimate of the aggregate range of reasonably possible losses involves significant judgment, given: •the number, variety and varying stages of the proceedings, including the fact that many are in preliminary stages, •the existence in many such proceedings of multiple defendants, including the Firm, whose share of liability (if any) has yet to be determined, •the numerous yet-unresolved issues in many of the proceedings, including issues regarding class certification and the scope of many of the claims, and •the attendant uncertainty of the various potential outcomes of such proceedings, including where the Firm has made assumptions concerning future rulings by the court or other adjudicator, or about the behavior or incentives of adverse parties or regulatory authorities, and those assumptions prove to be incorrect. In addition, the outcome of a particular proceeding may be a result which the Firm did not take into account in its estimate because the Firm had deemed the likelihood of that outcome to be remote. Accordingly, the Firm’s estimate of the aggregate range of reasonably possible losses will change from time to time, and actual losses may vary significantly. As of September 30, 2021, the Firm and its subsidiaries and affiliates are defendants or respondents in numerous legal proceedings, including private, civil litigations, government investigations or regulatory enforcement matters. The litigations range from individual actions involving a single plaintiff to class action lawsuits with potentially millions of class members. Investigations and regulatory enforcement matters involve both formal and informal proceedings, by both governmental agencies and self-regulatory organizations. These legal proceedings are at varying stages of adjudication, arbitration or investigation, and involve each of the Firm’s lines of business and several geographies and a wide variety of claims (including common law tort and contract claims and statutory antitrust, securities and consumer protection claims), some of which present novel legal theories.

A South Africa Competition Commission matter is the remaining FX-related governmental inquiry, and is currently pending before the South Africa Competition Tribunal. In August 2018, the United States District Court for the Southern District of New York granted final approval to the Firm’s settlement of a consolidated class action brought by U.S.-based plaintiffs, which principally alleged violations of federal antitrust laws based on an alleged conspiracy to manipulate foreign exchange rates and also sought damages on behalf of persons who transacted in FX futures and options on futures. Certain members of the settlement class filed requests to the Court to be excluded from the class, and certain of them filed a complaint against the Firm and other foreign exchange dealers in November 2018. A number of these actions remain pending. Further, a putative class action has been filed against the Firm and other foreign exchange dealers on behalf of certain consumers who purchased foreign currencies at allegedly inflated rates.

In 2017, after the approval of that settlement was reversed on appeal, the case was remanded  to the United States District Court for the Eastern District of New York for further proceedings consistent with the appellate decision. The original class action was divided into two separate actions, one seeking primarily monetary relief and the other seeking primarily injunctive relief. In September 2018, the parties to the class action seeking monetary relief finalized an agreement which amends and supersedes the prior settlement agreement. Pursuant to this settlement, the defendants collectively contributed an additional $900 million to the approximately $5.3 billion previously held in escrow from the original settlement. In December 2019, the amended agreement was approved by the District Court. Certain merchants appealed the District Court’s approval order, and those appeals are pending. Based on the percentage of merchants that opted out of the amended class settlement, $700 million has been returned to the defendants from the settlement escrow in accordance with the settlement agreement. The class action seeking primarily injunctive relief continues separately, and in September 2021, the District Court granted plaintiffs’ motion for class certification in part, and denied the motion in part. In addition, certain merchants have filed individual actions raising similar allegations against Visa and Mastercard, as well as against the Firm and other banks, and some of those actions remain pending. LIBOR and Other Benchmark Rate Investigations and Litigation. JPMorgan Chase has responded to inquiries from various governmental agencies and entities around the world relating primarily to the British Bankers Association’s ("BBA") London Interbank Offered Rate (“LIBOR”) for various currencies and the European Banking Federation’s Euro Interbank Offered Rate (“EURIBOR”). The Swiss Competition Commission’s investigation relating to EURIBOR, to which the Firm and other banks are subject, continues. In December 2016, the European Commission issued a decision against the Firm and other banks finding an infringement of European antitrust rules relating to EURIBOR. The Firm has filed an appeal of that decision with the European General Court, and that appeal is pending. In addition, the Firm has been named as a defendant along with other banks in various individual and putative class actions related to benchmark rates, including U.S. dollar LIBOR. In actions related to U.S. dollar LIBOR during the period that it was administered by the BBA, the Firm has obtained dismissal of certain actions and resolved certain other actions, and others are in various stages of litigation. The United States District Court for the Southern District of New York has granted class certification of antitrust claims related to bonds and interest rate swaps sold directly by the defendants, including the Firm.

Metals and U.S. Treasuries Investigations and Litigation and Related Inquiries. The Firm previously reported that it and/or certain of its subsidiaries had entered into resolutions with the U.S. Department of Justice (“DOJ”), the U.S. Commodity Futures Trading Commission (“CFTC”) and the U.S. Securities and Exchange Commission (“SEC”), which, collectively, resolved those agencies’ respective investigations relating to historical trading practices by former employees in the precious metals and U.S. treasuries markets and related conduct from 2008 to 2016. The Firm entered into a Deferred Prosecution Agreement (“DPA”) with the DOJ in which it agreed to the filing of a criminal information charging JPMorgan Chase & Co. with two counts of wire fraud and agreed, along with JPMorgan Chase Bank, N.A. and J.P. Morgan Securities LLC, to certain terms and obligations as set forth therein. Under the terms of the DPA, the criminal information will be dismissed after three years, provided that JPMorgan Chase & Co., JPMorgan Chase Bank, N.A. and J.P. Morgan Securities LLC fully comply with all of their obligations. Across the three resolutions with the DOJ, CFTC and SEC, JPMorgan Chase & Co., JPMorgan Chase Bank, N.A. and J.P. Morgan Securities LLC agreed to pay a total monetary amount of approximately $920 million. A portion of the total monetary amount includes victim compensation payments. Several putative class action complaints have been filed in the United States District Court for the Southern District of New York against the Firm and certain former employees, alleging a precious metals futures and options price manipulation scheme in violation of the Commodity Exchange Act. Some of the complaints also allege unjust enrichment and deceptive acts or practices under the General Business Law of the State of New York. The Court consolidated these putative class actions in February 2019, and the consolidated action is stayed through December 2021. In July 2021, the parties informed the Court that they have entered into a settlement to resolve the action.

    Off-Balance Sheet Lending-Related Financial Instruments, Guarantees and Other Commitments [Abstract]                
        Off-balance Sheet Lending-related Financial Instruments, Guarantees, and Other Commitments                      | Off–balance sheet lending-related financial instruments, guarantees, and other commitments JPMorgan Chase provides lending-related financial instruments (e.g., commitments and guarantees) to address the financing needs of its customers and clients. The contractual amount of these financial instruments represents the maximum possible credit risk to the Firm should the customer or client draw upon the commitment or the Firm be required to fulfill its obligation under the guarantee, and should the customer or client subsequently fail to perform according to the terms of the contract. Most of these commitments and guarantees have historically been refinanced, extended, cancelled, or expired without being drawn or a default occurring. As a result, the total contractual amount of these instruments is not, in the Firm’s view, representative of its expected future credit exposure or funding requirements. Refer to Note 28 of JPMorgan Chase’s 2020 Form 10-K for a further discussion of lending-related commitments and guarantees, and the Firm’s related accounting policies. To provide for expected credit losses in wholesale and certain consumer lending-related commitments, an allowance for credit losses on lending-related commitments is maintained. Refer to Note 12 for further information regarding the allowance for credit losses on lending-related commitments. The following table summarizes the contractual amounts and carrying values of off-balance sheet lending-related financial instruments, guarantees and other commitments at September 30, 2021, and December 31, 2020. The amounts in the table below for credit card, home equity and certain scored business banking lending-related commitments represent the total available credit for these products. The Firm has not experienced, and does not anticipate, that all available lines of credit for these products will be utilized at the same time. The Firm can reduce or cancel credit card and certain scored business banking lines of credit by providing the borrower notice or, in some cases as permitted by law, without notice. In addition, the Firm typically closes credit card lines when the borrower is 60 days or more past due. The Firm may reduce or close HELOCs when there are significant decreases in the value of the underlying property, or when there has been a demonstrable decline in the creditworthiness of the borrower.

(c)Predominantly all consumer and wholesale lending-related commitments are in the U.S. (d)At September 30, 2021, and December 31, 2020, reflected the contractual amount net of risk participations totaling $48 million and $72 million, respectively, for other unfunded commitments to extend credit; $7.9 billion and $8.5 billion, respectively, for standby letters of credit and other financial guarantees; and $609 million and $357 million, respectively, for other letters of credit. In regulatory filings with the Federal Reserve these commitments are shown gross of risk participations. (e)At September 30, 2021, and December 31, 2020, collateral held by the Firm in support of securities lending indemnification agreements was $324.0 billion and $264.3 billion, respectively. Securities lending collateral primarily consists of cash, G7 government securities, and securities issued by U.S. GSEs and government agencies. (f)At September 30, 2021, and December 31, 2020, includes guarantees to the Fixed Income Clearing Corporation under the sponsored member repo program and commitments and guarantees associated with the Firm’s membership in certain clearing houses. (g)At September 30, 2021, and December 31, 2020, primarily includes unfunded commitments to purchase secondary market loans, unfunded commitments related to certain tax-oriented equity investments, and other equity investment commitments, (h)Prior-period amounts have been revised to conform with the current presentation. (i)For lending-related products, the carrying value represents the allowance for lending-related commitments and the guarantee liability; for derivative-related products, and lending-related commitments for which the fair value option was elected, the carrying value represents the fair value. Other unfunded commitments to extend credit Other unfunded commitments to extend credit generally consist of commitments for working capital and general corporate purposes, extensions of credit to support commercial paper facilities and bond financings in the event that those obligations cannot be remarketed to new investors, as well as committed liquidity facilities to clearing organizations.

Merchant charge-backs Under the rules of payment networks, the Firm, in its role as a merchant acquirer, retains a contingent liability for disputed processed credit and debit card transactions that result in a charge-back to the merchant. If a dispute is resolved in the cardholder’s favor, Merchant Services will (through the cardholder’s issuing bank) credit or refund the amount to the cardholder and will charge back the transaction to the merchant. If Merchant Services is unable to collect the amount from the merchant, Merchant Services will bear the loss for the amount credited or refunded to the cardholder. Merchant Services mitigates this risk by withholding future settlements, retaining cash reserve accounts or obtaining other collateral. In addition, Merchant Services recognizes a valuation allowance that covers the payment or performance risk to the Firm related to charge-backs.

The liability related to repurchase demands associated with private label securitizations is separately evaluated by the Firm in establishing its litigation reserves.

The Firm also guarantees to the FICC the prompt and full payment and performance of its sponsored member clients’ respective obligations under the FICC’s rules. The Firm minimizes its liability under these overnight guarantees by obtaining a security interest in the cash or high-quality securities collateral that the clients place with the clearing house therefore the Firm expects the risk of loss to be remote. The Firm’s maximum possible exposure, without taking into consideration the associated collateral, is included in the Exchange & clearing house guarantees and commitments line on page 173. Refer to Note 11 of JPMorgan Chase’s 2020 Form 10-K for additional information on credit risk mitigation practices on resale agreements and the types of collateral pledged under repurchase agreements.

    Off-Balance Sheet Lending-Related Financial Instruments, Guarantees and Other Commitments [Abstract]                
        Off-balance sheet lending related financial instruments, guarantees and other commitments                       | The following table summarizes the contractual amounts and carrying values of off-balance sheet lending-related financial instruments, guarantees and other commitments at September 30, 2021, and December 31, 2020. The amounts in the table below for credit card, home equity and certain scored business banking lending-related commitments represent the total available credit for these products. The Firm has not experienced, and does not anticipate, that all available lines of credit for these products will be utilized at the same time. The Firm can reduce or cancel credit card and certain scored business banking lines of credit by providing the borrower notice or, in some cases as permitted by law, without notice. In addition, the Firm typically closes credit card lines when the borrower is 60 days or more past due. The Firm may reduce or close HELOCs when there are significant decreases in the value of the underlying property, or when there has been a demonstrable decline in the creditworthiness of the borrower.

Significant Firm-sponsored VIEs Credit card securitizations As a result of the Firm’s continuing involvement, the Firm is considered to be the primary beneficiary of its Firm-sponsored credit card securitization trust, the Chase Issuance Trust. Firm-sponsored mortgage and other securitization trusts The Firm securitizes (or has securitized) originated and purchased residential mortgages, commercial mortgages and other consumer loans primarily in its CCB and CIB businesses. Depending on the particular transaction, as well as the respective business involved, the Firm may act as the servicer of the loans and/or retain certain beneficial interests in the securitization trusts. The following tables present the total unpaid principal amount of assets held in Firm-sponsored private-label securitization entities, including those in which the Firm has continuing involvement, and those that are consolidated by the Firm. Continuing involvement includes servicing the loans, holding senior interests or subordinated interests (including amounts required to be held pursuant to credit risk retention rules), recourse or guarantee arrangements, and derivative contracts. In certain instances, the Firm’s only continuing involvement is servicing the loans. The Firm’s maximum loss exposure from retained and purchased interests is the carrying value of these interests.

(d)Includes interests held in re-securitization transactions. (e)As of both September 30, 2021 and December 31, 2020, 73% of the Firm’s retained securitization interests, which are predominantly carried at fair value and include amounts required to be held pursuant to credit risk retention rules, were risk-rated “A” or better, on an S&P-equivalent basis. The retained interests in prime residential mortgages consisted of $1.1 billion and $1.3 billion of investment-grade retained interests, and $131 million and $41 million of noninvestment-grade retained interests at September 30, 2021, and December 31, 2020, respectively. The retained interests in commercial and other securitization trusts consisted of $2.8 billion and $2.0 billion of investment-grade retained interests, and $854 million and $753 million of noninvestment-grade retained interests at September 30, 2021 and December 31, 2020, respectively. Residential mortgage The Firm securitizes residential mortgage loans originated by CCB, as well as residential mortgage loans purchased from third parties by either CCB or CIB. Commercial mortgages and other consumer securitizations CIB originates and securitizes commercial mortgage loans, and engages in underwriting and trading activities involving the securities issued by securitization trusts. Re-securitizations The following table presents the principal amount of securities transferred to re-securitization VIEs. Three months ended September 30, Nine months ended September 30, (in millions) 2021 2020 2021 2020 Transfers of securities to VIEs U.S. GSEs and government agencies $ 11,258 $ 12,488 $ 43,157 $ 27,710 The Firm did not transfer any private label securities to re-securitization VIEs during the three and nine months ended September 30, 2021 and 2020, and retained interests in any such Firm-sponsored VIEs as of September 30, 2021 and December 31, 2020 were immaterial. The following table presents information on the Firm's interests in nonconsolidated re-securitization VIEs. Nonconsolidated re-securitization VIEs (in millions) September 30, 2021 December 31, 2020 U.S. GSEs and government agencies Interest in VIEs $ 2,074 $ 2,631 As of September 30, 2021, and December 31, 2020, the Firm did not consolidate any U.S. GSE and government agency re-securitization VIEs or any Firm-sponsored private-label re-securitization VIEs. Multi-seller conduits In the normal course of business, JPMorgan Chase makes markets in and invests in commercial paper issued by the Firm-administered multi-seller conduits. The Firm held $12.5 billion and $13.5 billion of the commercial paper issued by the Firm-administered multi-seller conduits at September 30, 2021, and December 31, 2020, respectively, which have been eliminated in consolidation. The Firm’s investments reflect the Firm’s funding needs and capacity and were not driven by market illiquidity. Other than the amounts required to be held pursuant to credit risk retention rules, the Firm is not obligated under any agreement to purchase the commercial paper issued by the Firm-administered multi-seller conduits. Deal-specific liquidity facilities, program-wide liquidity and credit enhancement provided by the Firm have been eliminated in consolidation. The Firm or the Firm-administered multi-seller conduits provide lending-related commitments to certain clients of the Firm-administered multi-seller conduits. The unfunded commitments were $12.5 billion and $12.2 billion at September 30, 2021, and December 31, 2020, respectively, and are reported as off-balance sheet lending-related commitments in other unfunded commitments to extend credit. Refer to Note 22 for more information on off-balance sheet lending-related commitments. Municipal bond vehicles Municipal bond vehicles or tender option bond (“TOB”) trusts allow institutions to finance their municipal bond investments at short-term rates. TOB transactions are known as customer TOB trusts and non-customer TOB trusts. Customer TOB trusts are sponsored by a third party. The Firm serves as sponsor for all non-customer TOB transactions. Consolidated VIE assets and liabilities The following table presents information on assets and liabilities related to VIEs consolidated by the Firm as of September 30, 2021, and December 31, 2020.

(b)Predominantly includes purchased supply chain finance receivables and purchased auto loan securitizations in CIB. (c)Includes assets classified as cash and other assets on the Consolidated balance sheets. (d)The assets of the consolidated VIEs included in the program types above are used to settle the liabilities of those entities. The assets and liabilities include third-party assets and liabilities of consolidated VIEs and exclude intercompany balances that eliminate in consolidation. (e)The interest-bearing beneficial interest liabilities issued by consolidated VIEs are classified in the line item on the Consolidated balance sheets titled, “Beneficial interests issued by consolidated VIEs”. The holders of these beneficial interests generally do not have recourse to the general credit of JPMorgan Chase. Included in beneficial interests in VIE assets are long-term beneficial interests of $2.7 billion and $5.2 billion at September 30, 2021, and December 31, 2020, respectively. (f)Includes liabilities classified as accounts payable and other liabilities on the Consolidated balance sheets. VIEs sponsored by third parties The Firm enters into transactions with VIEs structured by other parties. These include, for example, acting as a derivative counterparty, liquidity provider, investor, underwriter, placement agent, remarketing agent, trustee or custodian. These transactions are conducted at arm’s-length, and individual credit decisions are based on the analysis of the specific VIE, taking into consideration the quality of the underlying assets. Where the Firm does not have the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance, or a variable interest that could potentially be significant, the Firm generally does not consolidate the VIE, but it records and reports these positions on its Consolidated balance sheets in the same manner it would record and report positions in respect of any other third-party transaction. Tax credit vehicles The Firm holds investments in unconsolidated tax credit vehicles, which are limited partnerships and similar entities that own and operate affordable housing, energy, and other projects. These entities are primarily considered VIEs. A third party is typically the general partner or managing member and has control over the significant activities of the tax credit vehicles, and accordingly the Firm does not consolidate tax credit vehicles. The Firm generally invests in these partnerships as a limited partner and earns a return primarily through the receipt of tax credits allocated to the projects. The maximum loss exposure, represented by equity investments and funding commitments, was $24.7 billion and $23.6 billion, of which $8.6 billion and $8.7 billion was unfunded at September 30, 2021 and December 31, 2020, respectively. The prior-period maximum loss exposure amount has been revised to conform with the current presentation. The Firm assesses each project and to reduce the risk of loss, may withhold varying amounts of its capital investment until the project qualifies for tax credits. Refer to Note 25 of JPMorgan Chase’s 2020 Form 10-K for further information on affordable housing tax credits and Note 22 of this Form 10-Q for more information on off-balance sheet lending-related commitments. Customer municipal bond vehicles (TOB trusts) The Firm may provide various services to customer TOB trusts, including remarketing agent, liquidity or tender option provider. In certain customer TOB transactions, the Firm, as liquidity provider, has entered into a reimbursement agreement with the Residual holder. In those transactions, upon the termination of the vehicle, the Firm has recourse to the third-party Residual holders for any shortfall. The Firm does not have any intent to protect Residual holders from potential losses on any of the underlying municipal bonds. The Firm does not consolidate customer TOB trusts, since the Firm does not have the power to make decisions that significantly impact the economic performance of the municipal bond vehicle. The Firm’s maximum exposure as a liquidity provider to customer TOB trusts at September 30, 2021 and December 31, 2020 was $6.9 billion and $6.7 billion, respectively. The fair value of assets held by such VIEs at September 30, 2021 and December 31, 2020 was $10.6 billion and $10.5 billion, respectively. Loan securitizations The Firm has securitized and sold a variety of loans, including residential mortgages, credit card receivables, and commercial mortgages. Securitization activity The following table provides information related to the Firm’s securitization activities for the three and nine months ended September 30, 2021 and 2020, related to assets held in Firm-sponsored securitization entities that were not consolidated by the Firm, and where sale accounting was achieved at the time of the securitization.

Excludes loan securitization activity related to U.S. GSEs and government agencies. (e)Includes commercial mortgage and other consumer loans. Loans and excess MSRs sold to U.S. government-sponsored enterprises and loans in securitization transactions pursuant to Ginnie Mae guidelines In addition to the amounts reported in the securitization activity tables above, the Firm, in the normal course of business, sells originated and purchased mortgage loans and certain originated excess MSRs on a nonrecourse basis, predominantly to U.S. GSEs. These loans and excess MSRs are sold primarily for the purpose of securitization by the U.S. GSEs, who provide certain guarantee provisions (e.g., credit enhancement of the loans). The Firm also sells loans into securitization transactions pursuant to Ginnie Mae guidelines; these loans are typically insured or guaranteed by another U.S. government agency. The Firm does not consolidate the securitization vehicles underlying these transactions as it is not the primary beneficiary. For a limited number of loan sales, the Firm is obligated to share a portion of the credit risk associated with the sold loans with the purchaser. Refer to Note 22 of this Form 10-Q for additional information about the Firm’s loan sales- and securitization-related indemnifications and Note 14 for additional information about the impact of the Firm’s sale of certain excess MSRs. The following table summarizes the activities related to loans sold to the U.S. GSEs, and loans in securitization transactions pursuant to Ginnie Mae guidelines.

(e)The carrying value of the loans accounted for at fair value approximated the proceeds received upon loan sale. Options to repurchase delinquent loans In addition to the Firm’s obligation to repurchase certain loans due to material breaches of representations and warranties as discussed in Note 22, the Firm also has the option to repurchase delinquent loans that it services for Ginnie Mae loan pools, as well as for other U.S. government agencies under certain arrangements. The Firm typically elects to repurchase delinquent loans from Ginnie Mae loan pools as it continues to service them and/or manage the foreclosure process in accordance with the applicable requirements, and such loans continue to be insured or guaranteed. When the Firm’s repurchase option becomes exercisable, such loans must be reported on the Consolidated balance sheets as a loan with a corresponding liability. Refer to Note 11 for additional information. The following table presents loans the Firm repurchased or had an option to repurchase, real estate owned, and foreclosed government-guaranteed residential mortgage loans recognized on the Firm’s Consolidated balance sheets as of September 30, 2021 and December 31, 2020.

        Securities Financing Activities                                                                                 | Securities financing activities Refer to Note 11 of JPMorgan Chase’s 2020 Form 10-K for a discussion of accounting policies relating to securities financing activities. Refer to Note 3 for further information regarding securities borrowed and securities lending agreements for which the fair value option has been elected. Refer to Note 23 for further information regarding assets pledged and collateral received in securities financing agreements. The table below summarizes the gross and net amounts of the Firm’s securities financing agreements as of September 30, 2021 and December 31, 2020. When the Firm has obtained an appropriate legal opinion with respect to a master netting agreement with a counterparty and where other relevant netting criteria under U.S. GAAP are met, the Firm nets, on the Consolidated balance sheets, the balances outstanding under its securities financing agreements with the same counterparty. In addition, the Firm exchanges securities and/or cash collateral with its counterparty to reduce the economic exposure with the counterparty, but such collateral is not eligible for net Consolidated balance sheet presentation. Where the Firm has obtained an appropriate legal opinion with respect to the counterparty master netting agreement, such collateral, along with securities financing balances that do not meet all these relevant netting criteria under U.S. GAAP, is presented in the table below as “Amounts not nettable on the Consolidated balance sheets,” and reduces the “Net amounts” presented. Where a legal opinion has not been either sought or obtained, the securities financing balances are presented gross in the “Net amounts” below. In transactions where the Firm is acting as the lender in a securities-for-securities lending agreement and receives securities that can be pledged or sold as collateral, the Firm recognizes the securities received at fair value within other assets and the obligation to return those securities within accounts payable and other liabilities on the Consolidated balance sheets.

(b)In some cases, collateral exchanged with a counterparty exceeds the net asset or liability balance with that counterparty. In such cases, the amounts reported in this column are limited to the related net asset or liability with that counterparty. (c)Includes securities financing agreements that provide collateral rights, but where an appropriate legal opinion with respect to the master netting agreement has not been either sought or obtained.

The Firm’s definition of managed basis starts with the reported U.S. GAAP results and includes certain reclassifications to present total net revenue for the Firm (and each of the reportable business segments) on an FTE basis. Accordingly, revenue from investments that receive tax credits and tax-exempt securities is presented in the managed results on a basis comparable to taxable investments and securities. Refer to Note 32 of JPMorgan Chase’s 2020 Form 10-K for additional information on the Firm’s managed basis. Capital allocation The amount of capital assigned to each segment is referred to as equity.

Unlike principal-protected structured notes and long-term beneficial interests, for which the Firm is obligated to return a stated amount of principal at maturity, nonprincipal-protected structured notes and long-term beneficial interests do not obligate the Firm to return a stated amount of principal at maturity, but for structured notes to return an amount based on the performance of an underlying variable or derivative feature embedded in the note. However, investors are exposed to the credit risk of the Firm as issuer for both nonprincipal-protected and principal-protected notes. (d)Where the Firm issues principal-protected zero-coupon or discount notes, the balance reflects the contractual principal payment at maturity or, if applicable, the contractual principal payment at the Firm’s next call date.

Goodwill The following table presents goodwill attributed to the reportable business segments and Corporate.

Three months ended September 30, Nine months ended September 30, (in millions) 2021 2020 2021 2020 Balance at beginning of period $ 49,256 $ 47,811 $ 49,248 $ 47,823 Changes during the period from: Business combinations(a) 1,065 — 1,065 — Other(b) (8) 8 — (4) Balance at September 30, $ 50,313 $ 47,819 $ 50,313 $ 47,819 (a)For the three and nine months ended September 30, 2021, represents estimated goodwill associated with the acquisitions of Nutmeg in Corporate, OpenInvest and Campbell Global in AWM and Frank in CCB. (b)Primarily foreign currency adjustments and adjustments to goodwill related to prior period acquisitions. Goodwill impairment testing Goodwill is tested for impairment during the fourth quarter of each fiscal year, or more often if events or circumstances, such as adverse changes in the business climate, indicate that there may be an impairment. Refer to Note 15 of JPMorgan Chase’s 2020 Form 10-K for a further discussion of the Firm’s goodwill impairment testing. Unanticipated declines in business performance, increases in credit losses, increases in capital requirements, as well as deterioration in economic or market conditions, adverse regulatory or legislative changes or increases in the estimated market cost of equity, could cause the estimated fair values of the Firm’s reporting units to decline in the future, which could result in a material impairment charge to earnings in a future period related to some portion of the associated goodwill. As of September 30, 2021, the Firm reviewed current economic conditions, including the potential impacts of the COVID-19 pandemic on business performance, estimated market cost of equity, as well as actual business results and projections of business performance. The Firm has concluded that goodwill was not impaired as of September 30, 2021, or December 31, 2020, nor was goodwill written off due to impairment during the nine months ended September 30, 2021 or 2020. Mortgage servicing rights MSRs represent the fair value of expected future cash flows for performing servicing activities for others. The fair value considers estimated future servicing fees and ancillary revenue, offset by estimated costs to service the loans, and generally declines over time as net servicing cash flows are received, effectively amortizing the MSR asset against contractual servicing and ancillary fee income. MSRs are either purchased from third parties or recognized upon sale or securitization of mortgage loans if servicing is retained. Refer to Notes 2 and 15 of JPMorgan Chase’s 2020 Form 10-K for a further description of the MSR asset, interest rate risk management, and the valuation of MSRs. The following table summarizes MSR activity for the three and nine months ended September 30, 2021 and 2020.

In each transaction, a portion of the SMBS was acquired by third parties at the transaction date; the Firm acquired the remaining balance of those SMBS as trading securities. (b)Represents both the impact of changes in estimated future prepayments due to changes in market interest rates, and the difference between actual and expected prepayments. (c)Represents changes in prepayments other than those attributable to changes in market interest rates. (d)Represents amounts the Firm pays as the servicer (e.g., scheduled principal and interest, taxes and insurance), which will generally be reimbursed within a short period of time after the advance from future cash flows from the trust or the underlying loans. The Firm’s credit risk associated with these servicer advances is minimal because reimbursement of the advances is typically senior to all cash payments to investors. In addition, the Firm maintains the right to stop payment to investors if the collateral is insufficient to cover the advance. However, certain of these servicer advances may not be recoverable if they were not made in accordance with applicable rules and agreements.

Changes in fair value based on variations in assumptions generally cannot be easily extrapolated, because the relationship of the change in the assumptions to the change in fair value are often highly interrelated and may not be linear. In this table, the effect that a change in a particular assumption may have on the fair value is calculated without changing any other assumption. In reality, changes in one factor may result in changes in another, which would either magnify or counteract the impact of the initial change.

Goodwill impairment testing Goodwill is tested for impairment during the fourth quarter of each fiscal year, or more often if events or circumstances, such as adverse changes in the business climate, indicate that there may be an impairment. Refer to Note 15 of JPMorgan Chase’s 2020 Form 10-K for a further discussion of the Firm’s goodwill impairment testing. Unanticipated declines in business performance, increases in credit losses, increases in capital requirements, as well as deterioration in economic or market conditions, adverse regulatory or legislative changes or increases in the estimated market cost of equity, could cause the estimated fair values of the Firm’s reporting units to decline in the future, which could result in a material impairment charge to earnings in a future period related to some portion of the associated goodwill. As of September 30, 2021, the Firm reviewed current economic conditions, including the potential impacts of the COVID-19 pandemic on business performance, estimated market cost of equity, as well as actual business results and projections of business performance. The Firm has concluded that goodwill was not impaired as of September 30, 2021, or December 31, 2020, nor was goodwill written off due to impairment during the nine months ended September 30, 2021 or 2020.

Mortgage servicing rights Mortgage servicing rights MSRs represent the fair value of expected future cash flows for performing servicing activities for others. The fair value considers estimated future servicing fees and ancillary revenue, offset by estimated costs to service the loans, and generally declines over time as net servicing cash flows are received, effectively amortizing the MSR asset against contractual servicing and ancillary fee income. MSRs are either purchased from third parties or recognized upon sale or securitization of mortgage loans if servicing is retained. Refer to Notes 2 and 15 of JPMorgan Chase’s 2020 Form 10-K for a further description of the MSR asset, interest rate risk management, and the valuation of MSRs.

The effective yield considers the contractual coupon, amortization of premiums and accretion of discounts, and the effect of related hedging derivatives. Taxable-equivalent amounts are used where applicable. The effective yield excludes unscheduled principal prepayments; and accordingly, actual maturities of securities may differ from their contractual or expected maturities as certain securities may be prepaid. However, for certain callable debt securities, the average yield is calculated to the earliest call date.(b)Substantially all of the Firm’s U.S. residential MBS and collateralized mortgage obligations are due in 10 years or more, based on contractual maturity. The estimated weighted-average life, which reflects anticipated future prepayments, is approximately 6 years for agency residential MBS, 4 years for agency residential collateralized mortgage obligations and 3 years for nonagency residential collateralized mortgage obligations.

The Firm accounts for loans based on the following categories: •Originated or purchased loans held-for-investment (i.e., “retained”) •Loans held-for-sale •Loans at fair value Refer to Note 12 of JPMorgan Chase's 2020 Form 10-K for a detailed discussion of loans, including accounting policies. Refer to Note 3 of this Form 10-Q for further information on the Firm's elections of fair value accounting under the fair value option. Refer to Note 2 of this Form 10-Q for information on loans carried at fair value and classified as trading assets. Loan portfolio The Firm’s loan portfolio is divided into three portfolio segments, which are the same segments used by the Firm to determine the allowance for loan losses: Consumer, excluding credit card; Credit card; and Wholesale. Within each portfolio segment the Firm monitors and assesses the credit risk in the following classes of loans, based on the risk characteristics of each loan class. Consumer, excluding credit card Credit card Wholesale(c)(d) • Residential real estate(a) • Auto and other(b) • Credit card loans • Secured by real estate • Commercial and industrial • Other(e) (a)Includes scored mortgage and home equity loans held in CCB and AWM, and scored mortgage loans held in CIB and Corporate. (b)Includes scored auto and business banking loans and overdrafts. (c)Includes loans held in CIB, CB, AWM, Corporate as well as risk-rated loans held in CCB, including business banking and auto dealer loans for which the wholesale methodology is applied when determining the allowance for loan losses. (d)The wholesale portfolio segment's classes align with loan classifications as defined by the bank regulatory agencies, based on the loan's collateral, purpose, and type of borrower. (e)Includes loans to financial institutions, states and political subdivisions, SPEs, nonprofits, personal investment companies and trusts, as well as loans to individuals and individual entities (predominantly Global Private Bank clients within AWM). Refer to Note 14 of JPMorgan Chase’s 2020 Form 10-K for more information on SPEs. The following tables summarize the Firm’s loan balances by portfolio segment.

The Firm wrote off accrued interest receivables of $10 million and $34 million for the three months ended September 30, 2021 and 2020, respectively, and $30 million and $82 million for the nine months ended September 30, 2021 and 2020, respectively. (b)Loans (other than those for which the fair value option has been elected) are presented net of unamortized discounts and premiums and net deferred loan fees or costs. These amounts were not material as of September 30, 2021, and December 31, 2020. The following tables provide information about the carrying value of retained loans purchased, sold and reclassified to held-for-sale during the periods indicated. Loans that were reclassified to held-for-sale and sold in a subsequent period are excluded from the sales line of this table. 2021 2020 Three months ended September 30, (in millions) Consumer, excluding credit card Credit card Wholesale Total Consumer, excluding credit card Credit card Wholesale Total Purchases $ 101 (b)(c) $ — $ 245 $ 346 $ 1,780 (b)(c) $ — $ 309 $ 2,089 Sales — — 7,826 7,826 — — 4,578 4,578 Retained loans reclassified to held-for-sale(a) 522 — 397 919 995 787 403 2,185 2021 2020 Nine months ended September 30, (in millions) Consumer, excluding credit card Credit card Wholesale Total Consumer, excluding credit card Credit card Wholesale Total Purchases $ 403 (b)(c) $ — $ 772 $ 1,175 $ 3,180 (b)(c) $ — $ 937 $ 4,117 Sales 181 — 22,307 22,488 348 — 13,579 13,927 Retained loans reclassified to held-for-sale(a) 771 — 2,061 2,832 1,822 787 1,154 3,763 (a)Reclassifications of loans to held-for-sale are non-cash transactions. (b)Predominantly includes purchases of residential real estate loans, including the Firm’s voluntary repurchases of certain delinquent loans from loan pools as permitted by Government National Mortgage Association (“Ginnie Mae”) guidelines for the three and nine months ended September 30, 2021 and 2020. The Firm typically elects to repurchase these delinquent loans as it continues to service them and/or manage the foreclosure process in accordance with applicable requirements of Ginnie Mae, FHA, RHS, and/or VA. (c)Excludes purchases of retained loans of $7.3 billion and $3.1 billion for the three months ended September 30, 2021 and 2020, respectively, and $19.3 billion and $10.5 billion for the nine months ended September 30, 2021 and 2020, respectively, which are predominantly sourced through the correspondent origination channel and underwritten in accordance with the Firm’s standards. Gains and losses on sales of loans Net gains/(losses) on sales of loans and lending-related commitments (including adjustments to record loans and lending-related commitments held-for-sale at the lower of cost or fair value) recognized in noninterest revenue for the three and nine months ended September 30, 2021 was $31 million and $225 million, respectively, of which $30 million and $211 million, respectively, related to loans. Net gains/(losses) on sales of loans and lending-related commitments for the three and nine months ended September 30, 2020 was $113 million and $(75) million, respectively, of which $24 million and $(76) million, respectively, related to loans. In addition, the sale of loans may also result in write downs, recoveries or changes in the allowance recognized in the provision for credit losses. Loan modifications The Firm has granted various forms of assistance to customers and clients impacted by the COVID-19 pandemic, including payment deferrals and covenant modifications. The majority of the Firm’s COVID-19 related loan modifications have not been considered TDRs because: •they represent short-term or other insignificant modifications, whether under the Firm’s regular loan modification assessments or as permitted by regulatory guidance, or •the Firm has elected to apply the option to suspend the application of accounting guidance for TDRs as provided by the CARES Act and extended by the Consolidated Appropriations Act. To the extent that certain modifications do not meet any of the above criteria, the Firm accounts for them as TDRs. As permitted by regulatory guidance, the Firm does not place loans with deferrals granted due to COVID-19 on nonaccrual status where such loans are not otherwise reportable as nonaccrual. The Firm considers expected losses of principal and accrued interest associated with all COVID-19 related loan modifications in its allowance for credit losses. Assistance provided in response to the COVID-19 pandemic could delay the recognition of delinquencies, nonaccrual status, and net charge-offs for those customers who would have otherwise moved into past due or nonaccrual status. Consumer, excluding credit card loan portfolio Consumer loans, excluding credit card loans, consist primarily of scored residential mortgages, home equity loans and lines of credit, auto and business banking loans, with a focus on serving the prime consumer credit market. The portfolio also includes home equity loans secured by junior liens, prime mortgage loans with an interest-only payment period and certain payment-option loans that may result in negative amortization. The following table provides information about retained consumer loans, excluding credit card, by class. (in millions) September 30, 2021 December 31, 2020 Residential real estate $ 221,671 $ 225,302 Auto and other(a) 76,637 76,825 Total retained loans $ 298,308 $ 302,127 (a)At September 30, 2021 and December 31, 2020, included $11.1 billion and $19.2 billion of loans, respectively, in Business Banking under the PPP. Delinquency rates are the primary credit quality indicator for consumer loans. Refer to Note 12 of JPMorgan Chase's 2020 Form 10-K for further information on consumer credit quality indicators. Residential real estate The following tables provide information on delinquency, which is the primary credit quality indicator for retained residential real estate loans. (in millions, except ratios) September 30, 2021 Term loans by origination year(d) Revolving loans Total 2021 2020 2019 2018 2017 Prior to 2017 Within the revolving period Converted to term loans Loan delinquency(a)(b) Current $ 50,900 $ 51,577 $ 21,058 $ 8,958 $ 13,231 $ 54,691 $ 6,707 $ 12,595 $ 219,717 30–149 days past due 11 13 17 17 10 479 16 172 735 150 or more days past due — — 7 5 13 927 5 262 1,219 Total retained loans $ 50,911 $ 51,590 $ 21,082 $ 8,980 $ 13,254 $ 56,097 $ 6,728 $ 13,029 $ 221,671 % of 30+ days past due to total retained loans(c) 0.02 % 0.03 % 0.11 % 0.24 % 0.17 % 2.45 % 0.31 % 3.33 % 0.87 % (in millions, except ratios) December 31, 2020 Term loans by origination year(d) Revolving loans Total 2020 2019 2018 2017 2016 Prior to 2016 Within the revolving period Converted to term loans Loan delinquency(a)(b) Current $ 56,576 (e) $ 31,820 $ 13,900 $ 20,410 $ 27,978 $ 49,218 (e) $ 7,902 (e) $ 15,260 (e) $ 223,064 30–149 days past due 9 25 20 22 29 674 21 245 1,045 150 or more days past due 3 14 10 18 18 844 22 264 1,193 Total retained loans $ 56,588 $ 31,859 $ 13,930 $ 20,450 $ 28,025 $ 50,736 $ 7,945 $ 15,769 $ 225,302 % of 30+ days past due to total retained loans(c) 0.02 % 0.12 % 0.22 % 0.20 % 0.17 % 2.91 % (e) 0.54 % (e) 3.23 % (e) 0.98 % (a)Individual delinquency classifications include mortgage loans insured by U.S. government agencies as follows: current included $41 million and $36 million; 30–149 days past due included $11 million and $16 million; and 150 or more days past due included $20 million and $24 million at September 30, 2021 and December 31, 2020, respectively. (b)At September 30, 2021 and December 31, 2020, loans under payment deferral programs offered in response to the COVID-19 pandemic which are still within their deferral period and performing according to their modified terms are generally not considered delinquent. (c)At September 30, 2021 and December 31, 2020, residential real estate loans excluded mortgage loans insured by U.S. government agencies of $31 million and $40 million, respectively, that are 30 or more days past due. These amounts have been excluded based upon the government guarantee. (d)Purchased loans are included in the year in which they were originated. (e)Prior-period amounts have been revised to conform with the current presentation. Approximately 36% of the total revolving loans are senior lien loans; the remaining balance are junior lien loans. The lien position the Firm holds is considered in the Firm’s allowance for credit losses. Revolving loans that have been converted to term loans have higher delinquency rates than those that are still within the revolving period. That is primarily because the fully-amortizing payment that is generally required for those products is higher than the minimum payment options available for revolving loans within the revolving period. Nonaccrual loans and other credit quality indicators The following table provides information on nonaccrual and other credit quality indicators for retained residential real estate loans. (in millions, except weighted-average data) September 30, 2021 December 31, 2020 Nonaccrual loans(a)(b)(c)(d) $ 4,794 $ 5,313 90 or more days past due and government guaranteed(e) 25 33 Current estimated LTV ratios(f)(g)(h) Greater than 125% and refreshed FICO scores: Equal to or greater than 660 $ 12 $ 6 Less than 660 3 12 101% to 125% and refreshed FICO scores: Equal to or greater than 660 31 38 Less than 660 20 44 80% to 100% and refreshed FICO scores: Equal to or greater than 660 2,146 2,177 Less than 660 103 239 Less than 80% and refreshed FICO scores: Equal to or greater than 660 205,919 208,238 Less than 660 10,054 11,980 No FICO/LTV available 3,311 2,492 U.S. government-guaranteed 72 76 Total retained loans $ 221,671 $ 225,302 Weighted average LTV ratio(f)(i) 51 % 54 % Weighted average FICO(g)(i) 764 763 Geographic region(j) California $ 70,719 $ 73,444 New York 32,221 32,287 Florida 15,439 13,981 Texas 13,645 13,773 Illinois 11,860 13,130 Colorado 8,496 8,235 Washington 8,071 7,917 New Jersey 6,884 7,227 Massachusetts 6,009 5,784 Connecticut 5,188 5,024 All other(k) 43,139 44,500 Total retained loans $ 221,671 $ 225,302 (a)Includes collateral-dependent residential real estate loans that are charged down to the fair value of the underlying collateral less costs to sell. The Firm reports, in accordance with regulatory guidance, residential real estate loans that have been discharged under Chapter 7 bankruptcy and not reaffirmed by the borrower (“Chapter 7 loans”) as collateral-dependent nonaccrual TDRs, regardless of their delinquency status. At September 30, 2021, approximately 7% of Chapter 7 residential real estate loans were 30 days or more past due. (b)Generally, all consumer nonaccrual loans have an allowance. In accordance with regulatory guidance, certain nonaccrual loans that are considered collateral-dependent have been charged down to the lower of amortized cost or the fair value of their underlying collateral less costs to sell. If the value of the underlying collateral has subsequently improved, the related allowance may be negative. (c)Interest income on nonaccrual loans recognized on a cash basis was $41 million and $39 million and $127 million and $119 million for the three and nine months ended September 30, 2021 and 2020, respectively. (d)Generally excludes loans under payment deferral programs offered in response to the COVID-19 pandemic. Includes loans to customers that have exited COVID-19 payment related deferral programs and are 90 or more days past due, predominantly all of which were considered collateral-dependent at time of exit. (e)These balances are excluded from nonaccrual loans as the loans are guaranteed by U.S government agencies. Typically the principal balance of the loans is insured and interest is guaranteed at a specified reimbursement rate subject to meeting agreed-upon servicing guidelines. At September 30, 2021 and December 31, 2020, these balances were no longer accruing interest based on the agreed-upon servicing guidelines. There were no loans that were not guaranteed by U.S. government agencies that are 90 or more days past due and still accruing interest at September 30, 2021 and December 31, 2020. (f)Represents the aggregate unpaid principal balance of loans divided by the estimated current property value. Current property values are estimated, at a minimum, quarterly, based on home valuation models using nationally recognized home price index valuation estimates incorporating actual data to the extent available and forecasted data where actual data is not available. Current estimated combined LTV for junior lien home equity loans considers all available lien positions, as well as unused lines, related to the property. (g)Refreshed FICO scores represent each borrower’s most recent credit score, which is obtained by the Firm on at least a quarterly basis. (h)Prior-period amounts have been revised to conform with the current presentation. (i)Excludes loans with no FICO and/or LTV data available. (j)The geographic regions presented in the table are ordered based on the magnitude of the corresponding loan balances at September 30, 2021. (k)At September 30, 2021 and December 31, 2020, included mortgage loans insured by U.S. government agencies of $72 million and $76 million, respectively. These amounts have been excluded from the geographic regions presented based upon the government guarantee. Loan modifications Modifications of residential real estate loans where the Firm grants concessions to borrowers who are experiencing financial difficulty are generally accounted for and reported as TDRs. Loans with short-term or other insignificant modifications that are not considered concessions are not TDRs nor are loans for which the Firm has elected to apply the option to suspend the application of accounting guidance for TDRs as provided by the CARES Act and extended by the Consolidated Appropriations Act. The carrying value of new TDRs was $116 million and $199 million for the three months ended September 30, 2021 and 2020, respectively, and $674 million and $537 million for the nine months ended September 30, 2021 and 2020, respectively. There were no additional commitments to lend to borrowers whose residential real estate loans have been modified in TDRs. Nature and extent of modifications The Firm’s proprietary modification programs as well as government programs, including U.S. GSE programs, generally provide various concessions to financially troubled borrowers including, but not limited to, interest rate reductions, term or payment extensions and delays of principal and/or interest payments that would otherwise have been required under the terms of the original agreement. The following table provides information about how residential real estate loans were modified in TDRs under the Firm’s loss mitigation programs described above during the periods presented. This table excludes Chapter 7 loans where the sole concession granted is the discharge of debt, loans with short-term or other insignificant modifications that are not considered concessions, and loans for which the Firm has elected to apply the option to suspend the application of accounting guidance for TDRs as provided by the CARES Act and extended by the Consolidated Appropriations Act. Three months ended September 30, Nine months ended September 30, 2021 2020 2021 2020 Number of loans approved for a trial modification 1,448 1,623 4,014 4,468 Number of loans permanently modified 917 1,615 3,817 5,200 Concession granted:(a) Interest rate reduction 75 % 40 % 74 % 51 % Term or payment extension 64 39 49 53 Principal and/or interest deferred 19 21 24 12 Principal forgiveness 1 1 2 2 Other(b) 24 65 39 65 (a)Represents concessions granted in permanent modifications as a percentage of the number of loans permanently modified. The sum of the percentages exceeds 100% because predominantly all of the modifications include more than one type of concession. Concessions offered on trial modifications are generally consistent with those granted on permanent modifications. (b)Includes variable interest rate to fixed interest rate modifications and payment delays that meet the definition of a TDR. Financial effects of modifications and redefaults The following table provides information about the financial effects of the various concessions granted in modifications of residential real estate loans under the loss mitigation programs described above and about redefaults of certain loans modified in TDRs for the periods presented. The following table presents only the financial effects of permanent modifications and do not include temporary concessions offered through trial modifications. This table also excludes Chapter 7 loans where the sole concession granted is the discharge of debt, loans with short-term or other insignificant modifications that are not considered concessions, and loans for which the Firm has elected to apply the option to suspend the application of accounting guidance for TDRs as provided by the CARES Act and extended by the Consolidated Appropriations Act.

The dollar amounts presented represent the balance of such loans at the end of the reporting period in which such loans defaulted. For residential real estate loans modified in TDRs, payment default is deemed to occur when the loan becomes two contractual payments past due. In the event that a modified loan redefaults, it will generally be liquidated through foreclosure or another similar type of liquidation transaction. Redefaults of loans modified within the last twelve months may not be representative of ultimate redefault levels. At September 30, 2021, the weighted-average estimated remaining lives of residential real estate loans permanently modified in TDRs were four years. The estimated remaining lives of these loans reflect estimated prepayments, both voluntary and involuntary (i.e., foreclosures and other forced liquidations). Active and suspended foreclosure At September 30, 2021 and December 31, 2020, the Firm had residential real estate loans, excluding those insured by U.S. government agencies, with a carrying value of $693 million and $846 million, respectively, that were not included in REO, but were in the process of active or suspended foreclosure. In response to the COVID-19 pandemic, the Firm has temporarily suspended certain foreclosure activities. This could delay recognition of foreclosed properties until the foreclosure moratoriums are lifted. Auto and other The following tables provide information on delinquency, which is the primary credit quality indicator for retained auto and other consumer loans.

(b)At September 30, 2021, auto and other loans excluded $126 million of PPP loans guaranteed by the SBA that are 30 or more days past due. These amounts have been excluded based upon the SBA guarantee. At December 31, 2020, all PPP loans guaranteed by the SBA were current. (c)At September 30, 2021, included $9.1 billion of loans originated in 2021 and $2.0 billion of loans originated in 2020 in Business Banking under the PPP. PPP loans are guaranteed by the SBA. Other than in certain limited circumstances, the Firm typically does not recognize charge-offs, classify as nonaccrual nor record an allowance for loan losses on these loans. (d)At December 31, 2020, included $19.2 billion of loans in Business Banking under the PPP. Nonaccrual and other credit quality indicators The following table provides information on nonaccrual and other credit quality indicators for retained auto and other consumer loans. (in millions, except ratios) Total Auto and other September 30, 2021 December 31, 2020 Nonaccrual loans(a)(b)(c) 117 151 Geographic region(d) California $ 12,137 $ 12,302 Texas 8,333 8,235 New York 7,511 8,824 Florida 5,125 4,668 Illinois 3,333 3,768 New Jersey 2,580 2,646 Arizona 2,103 2,465 Pennsylvania 2,076 1,924 Ohio 2,029 2,163 Louisiana 1,870 1,808 All other 29,540 28,022 Total retained loans $ 76,637 $ 76,825 (a)There were no loans that were 90 or more days past due and still accruing interest at September 30, 2021 and December 31, 2020. (b)Generally, all consumer nonaccrual loans have an allowance. In accordance with regulatory guidance, certain nonaccrual loans that are considered collateral-dependent have been charged down to the lower of amortized cost or the fair value of their underlying collateral less costs to sell. If the value of the underlying collateral has subsequently improved, the related allowance may be negative. (c)Interest income on nonaccrual loans recognized on a cash basis was not material for the three and nine months ended months ended September 30, 2021 and 2020. (d)The geographic regions presented in this table are ordered based on the magnitude of the corresponding loan balances at September 30, 2021. Loan modifications Certain auto and other loan modifications are considered to be TDRs as they provide various concessions to borrowers who are experiencing financial difficulty. Loans with short-term or other insignificant modifications that are not considered concessions are not TDRs. The impact of these modifications, as well as new TDRs, were not material to the Firm for the three and nine months ended September 30, 2021 and 2020. Additional commitments to lend to borrowers whose loans have been modified in TDRs as of September 30, 2021 and December 31, 2020 were not material. Credit card loan portfolio The credit card portfolio segment includes credit card loans originated and purchased by the Firm. Delinquency rates are the primary credit quality indicator for credit card loans.

Loan modifications The Firm may offer one of a number of loan modification programs granting concessions to credit card borrowers who are experiencing financial difficulty. The Firm grants concessions for most of the credit card loans under long-term programs. These modifications involve placing the customer on a fixed payment plan, generally for 60 months, and typically include reducing the interest rate on the credit card. Substantially all modifications under the Firm’s long-term programs are considered to be TDRs. Loans with short-term or other insignificant modifications that are not considered concessions are not TDRs. If the cardholder does not comply with the modified payment terms, then the credit card loan continues to age and will ultimately be charged-off in accordance with the Firm’s standard charge-off policy. In most cases, the Firm does not reinstate the borrower’s line of credit. Financial effects of modifications and redefaults The following table provides information about the financial effects of the concessions granted on credit card loans modified in TDRs and redefaults for the periods presented. For all periods disclosed, new enrollments were less than 1% of total retained credit card loans. (in millions, except weighted-average data) Three months ended September 30, Nine months ended September 30, 2021 2020 2021 2020 Balance of new TDRs(a) $ 82 $ 220 $ 315 $ 648 Weighted-average interest rate of loans – before TDR 17.75 % 17.65 % 17.79 % 18.21 % Weighted-average interest rate of loans – after TDR 5.15 4.80 5.19 4.55 Balance of loans that redefaulted within one year of modification(b) $ 13 $ 22 $ 45 $ 83 (a)Represents the outstanding balance prior to modification. (b)Represents loans modified in TDRs that experienced a payment default in the periods presented, and for which the payment default occurred within one year of the modification. The amounts presented represent the balance of such loans as of the end of the quarter in which they defaulted. For credit card loans modified in TDRs, payment default is deemed to have occurred when the borrower misses two consecutive contractual payments. Defaulted modified credit card loans remain in the modification program and continue to be charged off in accordance with the Firm’s standard charge-off policy. Wholesale loan portfolio Wholesale loans include loans made to a variety of clients, ranging from large corporate and institutional clients, to small businesses and high-net-worth individuals. The primary credit quality indicator for wholesale loans is the internal risk rating assigned to each loan. Refer to Note 12 of JPMorgan Chase’s 2020 Form 10-K for further information on these risk ratings.

As of September 30, 2021, substantially all of these loans were considered performing. (b)When the discounted cash flows or collateral value equals or exceeds the amortized cost of the loan, the loan does not require an allowance. This typically occurs when the loans have been partially charged off and/or there have been interest payments received and applied to the loan balance. (c)Interest income on nonaccrual loans recognized on a cash basis was not material for the three and nine months ended September 30, 2021 and 2020. Loan modifications Certain loan modifications are considered to be TDRs as they provide various concessions to borrowers who are experiencing financial difficulty. Loans with short-term or other insignificant modifications that are not considered concessions are not TDRs nor are loans for which the Firm has elected to apply the option to suspend the application of accounting guidance for TDRs as provided by the CARES Act and extended by the Consolidated Appropriations Act. The carrying value of TDRs was $928 million and $954 million as of September 30, 2021, and December 31, 2020, respectively. The carrying value of new TDRs was $180 million and $188 million for the three months ended September 30, 2021 and 2020, respectively, and $832 million and $352 million for the nine months ended September 30, 2021 and 2020, respectively. New TDRs for the three and nine months ended September 30, 2021 reflected deferral of principal and interest payments, extending maturity dates and the receipt of assets in partial satisfaction of the loan predominantly in Other and Commercial and Industrial loan classes. The impact of these modifications resulting in new TDRs was not material to the Firm for the three and nine months ended September 30, 2021 and 2020.

437,627 (a)At September 30, 2021, and December 31, 2020, included total U.S. GSE obligations of $68.6 billion and $117.6 billion, respectively, which were mortgage-related. (b)Physical commodities inventories are generally accounted for at the lower of cost or net realizable value. “Net realizable value” is a term defined in U.S. GAAP as not exceeding fair value less costs to sell (“transaction costs”). Transaction costs for the Firm’s physical commodities inventories are either not applicable or immaterial to the value of the inventory. Therefore, net realizable value approximates fair value for the Firm’s physical commodities inventories. When fair value hedging has been applied (or when net realizable value is below cost), the carrying value of physical commodities approximates fair value, because under fair value hedge accounting, the cost basis is adjusted for changes in fair value. Refer to Note 4 for a further discussion of the Firm’s hedge accounting relationships. To provide consistent fair value disclosure information, all physical commodities inventories have been included in each period presented. (c)Balances reflect the reduction of securities owned (long positions) by the amount of identical securities sold but not yet purchased (short positions). (d)Certain investments that are measured at fair value using the net asset value per share (or its equivalent) as a practical expedient are not required to be classified in the fair value hierarchy. At September 30, 2021, and December 31, 2020, the fair values of these investments, which include certain hedge funds, private equity funds, real estate and other funds, were $813 million and $670 million, respectively. Included in these balances at September 30, 2021, and December 31, 2020, were trading assets of $56 million and $52 million, respectively, and other assets of $757 million and $618 million, respectively. (e)At September 30, 2021, and December 31, 2020, included $27.2 billion and $15.1 billion, respectively, of residential first-lien mortgages, and $8.1 billion and $6.3 billion, respectively, of commercial first-lien mortgages. Residential mortgage loans include conforming mortgage loans originated with the intent to sell to U.S. GSEs and government agencies of $13.1 billion and $8.4 billion, respectively. (f)As permitted under U.S. GAAP, the Firm has elected to net derivative receivables and derivative payables and the related cash collateral received and paid when a legally enforceable master netting agreement exists. The level 3 balances would be reduced if netting were applied, including the netting benefit associated with cash collateral. (g)Prior-period amounts have been revised to conform with the current presentation. The following table presents the assets and liabilities reported at fair value as of September 30, 2021, and December 31, 2020, by major product category and fair value hierarchy.

(b)Physical commodities inventories are generally accounted for at the lower of cost or net realizable value. “Net realizable value” is a term defined in U.S. GAAP as not exceeding fair value less costs to sell (“transaction costs”). Transaction costs for the Firm’s physical commodities inventories are either not applicable or immaterial to the value of the inventory. Therefore, net realizable value approximates fair value for the Firm’s physical commodities inventories. When fair value hedging has been applied (or when net realizable value is below cost), the carrying value of physical commodities approximates fair value, because under fair value hedge accounting, the cost basis is adjusted for changes in fair value. Refer to Note 4 for a further discussion of the Firm’s hedge accounting relationships. To provide consistent fair value disclosure information, all physical commodities inventories have been included in each period presented.

Furthermore, the inputs presented for each valuation technique in the table are, in some cases, not applicable to every instrument valued using the technique as the characteristics of the instruments can differ.(b)Comprises U.S. GSE and government agency securities of $299 million, nonagency securities of $24 million and non-trading loans of $838 million.(c)Comprises nonagency securities of $19 million, trading loans of $41 million and non-trading loans of $420 million.(d)Comprises trading loans of $941 million and non-trading loans of $813 million.(e)Long-term debt, short-term borrowings and deposits include structured notes issued by the Firm that are financial instruments that typically contain embedded derivatives. The estimation of the fair value of structured notes includes the derivative features embedded within the instrument. The significant unobservable inputs are broadly consistent with those presented for derivative receivables.(f)Includes equity securities of $1.0 billion including $379 million in Other Assets, for which quoted prices are not readily available and the fair value is generally based on internal valuation techniques such as EBITDA multiples and comparable analysis. All other level 3 assets and liabilities are insignificant both individually and in aggregate.(g)Price is a significant unobservable input for certain instruments. When quoted market prices are not readily available, reliance is generally placed on price-based internal valuation techniques. The price input is expressed assuming a par value of $100.(h)Forward equity price is expressed as a percentage of the current equity price.(i)Amounts represent weighted averages except for derivative related inputs where arithmetic averages are used.

        Changes in level 3 recurring fair value measurements                                                            | The following tables include a rollforward of the Consolidated balance sheets amounts (including changes in fair value) for financial instruments classified by the Firm within level 3 of the fair value hierarchy for the three and nine months ended September 30, 2021 and 2020. When a determination is made to classify a financial instrument within level 3, the determination is based on the significance of the unobservable inputs to the overall fair value measurement. However, level 3 financial instruments typically include, in addition to the unobservable or level 3 components, observable components (that is, components that are actively quoted and can be validated to external sources); accordingly, the gains and losses in the table below include changes in fair value due in part to observable factors that are part of the valuation methodology. Also, the Firm risk-manages the observable components of level 3 financial instruments using securities and derivative positions that are classified within level 1 or 2 of the fair value hierarchy; as these level 1 and level 2 risk management instruments are not included below, the gains or losses in the following tables do not reflect the effect of the Firm’s risk management activities related to such level 3 instruments.

For certain loans, the fair value is measured based on the value of the underlying collateral. Carrying value of the loan takes into account the loan’s allowance for loan losses, which represents the loan’s expected credit losses over its remaining expected life. The difference between the estimated fair value and carrying value of a loan is generally attributable to changes in market interest rates, including credit spreads, market liquidity premiums and other factors that affect the fair value of a loan but do not affect its carrying value.

    Organization, Consolidation and Presentation of Financial Statements [Abstract]                                     
        Basis of presentation policy                                                                                    | The accounting and financial reporting policies of JPMorgan Chase and its subsidiaries conform to U.S. GAAP. Additionally, where applicable, the policies conform to the accounting and reporting guidelines prescribed by regulatory authorities.

        Use of estimates in the preparation of consolidated financial statements policy                                 | The unaudited Consolidated Financial Statements prepared in conformity with U.S. GAAP require management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expense, and the disclosures of contingent assets and liabilities. Actual results could be different from these estimates. In the opinion of management, all normal, recurring adjustments have been included such that this interim financial information is fairly stated.

        Reclassifications policy                                                                                        | Certain amounts reported in prior periods have been reclassified to conform with the current presentation, including certain deferred investment tax credits. In the first quarter of 2021 the Firm reclassified certain deferred investment tax credits from accounts payable and other liabilities to other assets to be a reduction to the carrying value of the associated tax-oriented investments. The reclassification also resulted in an increase in income tax expense and a corresponding increase in other income, with no effect on net income. Prior-period amounts have been revised to conform with the current presentation, including the Firm’s effective income tax rate. The reclassification did not change the Firm’s results of operations on a managed basis.

        Consolidation policy                                                                                            | The Consolidated Financial Statements include the accounts of JPMorgan Chase and other entities in which the Firm has a controlling financial interest. All material intercompany balances and transactions have been eliminated. Assets held for clients in an agency or fiduciary capacity by the Firm are not assets of JPMorgan Chase and are not included on the Consolidated balance sheets. The Firm determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity. The Consolidated Financial Statements include the accounts of JPMorgan Chase and other entities in which the Firm has a controlling financial interest. All material intercompany balances and transactions have been eliminated. The Consolidated Financial Statements include the accounts of JPMorgan Chase and other entities in which the Firm has a controlling financial interest. All material intercompany balances and transactions have been eliminated. Assets held for clients in an agency or fiduciary capacity by the Firm are not assets of JPMorgan Chase and are not included on the Consolidated balance sheets. Assets held for clients in an agency or fiduciary capacity by the Firm are not assets of JPMorgan Chase and are not included on the Consolidated balance sheets.

        Offsetting assets and liabilities policy                                                                        | U.S. GAAP permits entities to present derivative receivables and derivative payables with the same counterparty and the related cash collateral receivables and payables on a net basis on the Consolidated balance sheets when a legally enforceable master netting agreement exists. U.S. GAAP also permits securities financing activities to be presented on a net basis when specified conditions are met, including the existence of a legally enforceable master netting agreement. The Firm has elected to net such balances when the specified conditions are met. Refer to Note 1 of JPMorgan Chase’s 2020 Form 10-K for further information on offsetting assets and liabilities.

        Allowance for credit losses policy                                                                              | The Firm's allowance for credit losses represents management's estimate of expected credit losses over the remaining expected life of the Firm's financial assets measured at amortized cost and certain off-balance sheet lending-related commitments.

The Firm reports, in accordance with regulatory guidance, residential real estate loans that have been discharged under Chapter 7 bankruptcy and not reaffirmed by the borrower (“Chapter 7 loans”) as collateral-dependent nonaccrual TDRs, regardless of their delinquency status. At September 30, 2021, approximately 7% of Chapter 7 residential real estate loans were 30 days or more past due. (b)Generally, all consumer nonaccrual loans have an allowance. In accordance with regulatory guidance, certain nonaccrual loans that are considered collateral-dependent have been charged down to the lower of amortized cost or the fair value of their underlying collateral less costs to sell. If the value of the underlying collateral has subsequently improved, the related allowance may be negative. (c)Interest income on nonaccrual loans recognized on a cash basis was $41 million and $39 million and $127 million and $119 million for the three and nine months ended September 30, 2021 and 2020, respectively.

Includes loans to customers that have exited COVID-19 payment related deferral programs and are 90 or more days past due, predominantly all of which were considered collateral-dependent at time of exit. (e)These balances are excluded from nonaccrual loans as the loans are guaranteed by U.S government agencies. Typically the principal balance of the loans is insured and interest is guaranteed at a specified reimbursement rate subject to meeting agreed-upon servicing guidelines. At September 30, 2021 and December 31, 2020, these balances were no longer accruing interest based on the agreed-upon servicing guidelines. There were no loans that were not guaranteed by U.S. government agencies that are 90 or more days past due and still accruing interest at September 30, 2021 and December 31, 2020. (f)Represents the aggregate unpaid principal balance of loans divided by the estimated current property value. Current property values are estimated, at a minimum, quarterly, based on home valuation models using nationally recognized home price index valuation estimates incorporating actual data to the extent available and forecasted data where actual data is not available. Current estimated combined LTV for junior lien home equity loans considers all available lien positions, as well as unused lines, related to the property. (g)Refreshed FICO scores represent each borrower’s most recent credit score, which is obtained by the Firm on at least a quarterly basis. (h)Prior-period amounts have been revised to conform with the current presentation. (i)Excludes loans with no FICO and/or LTV data available.

        Troubled debt restructuring on financing receivables, financial effects of modifications and re-defaults        | The following table provides information about the financial effects of the various concessions granted in modifications of residential real estate loans under the loss mitigation programs described above and about redefaults of certain loans modified in TDRs for the periods presented. The following table presents only the financial effects of permanent modifications and do not include temporary concessions offered through trial modifications. This table also excludes Chapter 7 loans where the sole concession granted is the discharge of debt, loans with short-term or other insignificant modifications that are not considered concessions, and loans for which the Firm has elected to apply the option to suspend the application of accounting guidance for TDRs as provided by the CARES Act and extended by the Consolidated Appropriations Act.

        Regulatory Capital                                                                                              | Regulatory capital Refer to Note 27 of JPMorgan Chase’s 2020 Form 10-K for a detailed discussion on regulatory capital. The Federal Reserve establishes capital requirements, including well-capitalized requirements, for the consolidated financial holding company. The OCC establishes similar minimum capital requirements and standards for the Firm’s principal IDI subsidiary, JPMorgan Chase Bank, N.A. Under the risk-based capital and leverage-based guidelines of the Federal Reserve, JPMorgan Chase is required to maintain minimum ratios for CET1 capital, Tier 1 capital, Total capital, Tier 1 leverage and the SLR. Failure to meet these minimum requirements could cause the Federal Reserve to take action. IDI subsidiaries are also subject to these capital requirements established by their respective primary regulators. The following table presents the minimum and well-capitalized risk-based ratios to which the Firm and its IDI subsidiaries were subject as of September 30, 2021 and December 31, 2020. Standardized Minimum capital ratios Advanced Minimum capital ratios Well-capitalized ratios BHC(a) IDI(b) BHC(a) IDI(b) BHC(c) IDI(d) Risk-based capital ratios CET1 capital 11.3 % 7.0 % 10.5 % 7.0 % NA 6.5 % Tier 1 capital 12.8 8.5 12.0 8.5 6.0 % 8.0 Total capital 14.8 10.5 14.0 10.5 10.0 10.0 Note: The table above is as defined by the regulations issued by the Federal Reserve, OCC and FDIC and to which the Firm and its IDI subsidiaries are subject. (a)Represents the minimum capital ratios applicable to the Firm. The CET1, Tier 1 and Total capital minimum capital ratios each include a respective minimum requirement plus a GSIB surcharge of 3.5% as calculated under Method 2; plus a 3.3% SCB for Basel III Standardized ratios and a fixed 2.5% capital conservation buffer for Basel III Advanced ratios. The countercyclical buffer is currently set to 0% by the federal banking agencies. (b)Represents requirements for JPMorgan Chase’s IDI subsidiaries. The CET1, Tier 1 and Total capital minimum capital ratios include a fixed capital conservation buffer requirement of 2.5% that is applicable to the IDI subsidiaries. The IDI subsidiaries are not subject to the GSIB surcharge. (c)Represents requirements for bank holding companies pursuant to regulations issued by the Federal Reserve. (d)Represents requirements for IDI subsidiaries pursuant to regulations issued under the FDIC Improvement Act. The following table presents the minimum and well-capitalized leverage-based ratios to which the Firm and its IDI subsidiaries were subject as of September 30, 2021 and December 31, 2020. Minimum capital ratios(a) Well-capitalized ratios BHC IDI BHC(b) IDI Leverage-based capital ratios Tier 1 leverage 4.0 % 4.0 % NA 5.0 % SLR 5.0 6.0 NA 6.0 Note: The table above is as defined by the regulations issued by the Federal Reserve, OCC and FDIC and to which the Firm and its IDI subsidiaries are subject. (a)Represents minimum SLR requirement of 3.0%, as well as supplementary leverage buffer requirements of 2.0% and 3.0% for BHC and IDI subsidiaries, respectively. (b)The Federal Reserve's regulations do not establish well-capitalized thresholds for these measures for BHCs. CECL regulatory capital transition delay As part of their response to the impact of the COVID-19 pandemic, the federal banking agencies issued a final rule that provided the option beginning January 1, 2020 to delay the effects of CECL on regulatory capital for two years, followed by a three-year transition period beginning January 1, 2022. The Firm has elected to apply the CECL capital transition provisions, and accordingly, for the period ended September 30, 2021, the capital metrics of the Firm exclude $3.3 billion, which is the $2.7 billion day 1 impact to retained earnings and 25% of the $1.9 billion increase in the allowance for credit losses from January 1, 2020 (excluding allowances on PCD loans). The impacts of the CECL capital transition provisions have also been incorporated into Tier 2 capital, adjusted average assets, and total leverage exposure. Refer to Note 27 of JPMorgan Chase’s 2020 Form 10-K for further information on CECL capital transition provisions. The following tables present risk-based capital metrics under both the Basel III Standardized and Basel III Advanced Approaches and leverage-based capital metrics for JPMorgan Chase and JPMorgan Chase Bank, N.A. As of September 30, 2021 and December 31, 2020, JPMorgan Chase and JPMorgan Chase Bank, N.A. were well-capitalized and met all capital requirements to which each was subject.

On June 1, 2020, the Federal Reserve, OCC and FDIC issued an interim final rule which became effective April 1, 2020 and remained in effect through March 31, 2021 that provides IDI subsidiaries with an option to apply this temporary exclusion subject to certain restrictions.

Debt securities classified as trading assets are discussed in Note 2. Predominantly all of the Firm’s AFS and HTM securities are held by Treasury and CIO in connection with its asset-liability management activities. At September 30, 2021, the investment securities portfolio consisted of debt securities with an average credit rating of AA+ (based upon external ratings where available, and where not available, based primarily upon internal risk ratings). During the second quarter of 2021, the Firm transferred $104.5 billion of investment securities from AFS to HTM for capital management purposes. AOCI included pretax unrealized gains of $425 million on the securities at the date of transfer. Refer to Note 10 of JPMorgan Chase’s 2020 Form 10-K for additional information regarding the investment securities portfolio. The amortized costs and estimated fair values of the investment securities portfolio were as follows for the dates indicated.

As of September 30, 2021, mortgage-backed securities issued by Fannie Mae and Freddie Mac each exceeded 10% of JPMorgan Chase’s total stockholders’ equity; the amortized cost and fair value of such securities were $69.5 billion and $71.1 billion, and $46.3 billion and $46.3 billion, respectively. (b)The Firm purchased $15.9 billion and $79.0 billion of HTM securities for the three and nine months ended September 30, 2021, respectively, and $514 million and $5.5 billion for the three and nine months ended September 30, 2020, respectively. (c)The amortized cost of investment securities is reported net of allowance for credit losses of $73 million and $78 million at September 30, 2021 and December 31, 2020, respectively. (d)Excludes $1.8 billion and $2.1 billion of accrued interest receivables at September 30, 2021 and December 31, 2020, respectively. The Firm did not reverse through interest income any accrued interest receivables for the three and nine months ended September 30, 2021 and 2020. AFS securities impairment The following tables present the fair value and gross unrealized losses by aging category for AFS securities at September 30, 2021 and December 31, 2020. The tables exclude U.S. Treasury and government agency securities and U.S. GSE and government agency MBS with unrealized losses of $1.3 billion and $150 million, at September 30, 2021 and December 31, 2020, respectively; changes in the value of these securities are generally driven by changes in interest rates rather than changes in their credit profile given the explicit or implicit guarantees provided by the U.S. government.

The effective yield considers the contractual coupon, amortization of premiums and accretion of discounts, and the effect of related hedging derivatives. Taxable-equivalent amounts are used where applicable. The effective yield excludes unscheduled principal prepayments; and accordingly, actual maturities of securities may differ from their contractual or expected maturities as certain securities may be prepaid. However, for certain callable debt securities, the average yield is calculated to the earliest call date. (b)Substantially all of the Firm’s U.S. residential MBS and collateralized mortgage obligations are due in 10 years or more, based on contractual maturity. The estimated weighted-average life, which reflects anticipated future prepayments, is approximately 6 years for agency residential MBS, 4 years for agency residential collateralized mortgage obligations and 3 years for nonagency residential collateralized mortgage obligations.

yield(a) Average yield (a) 0.66 % 0.67 % 1.44 % 2.71 % 1.68 % (a)Average yield is computed using the effective yield of each security owned at the end of the period, weighted based on the amortized cost of each security. The effective yield considers the contractual coupon, amortization of premiums and accretion of discounts, and the effect of related hedging derivatives. Taxable-equivalent amounts are used where applicable. The effective yield excludes unscheduled principal prepayments; and accordingly, actual maturities of securities may differ from their contractual or expected maturities as certain securities may be prepaid. However, for certain callable debt securities, the average yield is calculated to the earliest call date.

(b)Includes collateral dependent loans, including those considered TDRs and those for which foreclosure is deemed probable, modified PCD loans and non-collateral dependent loans that have been modified or are reasonably expected to be modified in a TDR. Also includes risk-rated loans that have been placed on nonaccrual status for the wholesale portfolio segment. The asset-specific credit card allowance for loans modified, or reasonably expected to be modified, in a TDR is calculated based on the loans’ original contractual interest rates and does not consider any incremental penalty rates. (c)The allowance for lending-related commitments is reported in accounts payable and other liabilities on the Consolidated balance sheets. (d)At September 30, 2021 and 2020, lending-related commitments excluded $19.9 billion and $10.8 billion, respectively, for the consumer, excluding credit card portfolio segment; $710.6 billion and $662.9 billion, respectively, for the credit card portfolio segment; and $41.0 billion and $24.4 billion, respectively, for the wholesale portfolio segment, which were not subject to the allowance for lending-related commitments. Prior-period amount for wholesale lending-related commitments, including the amount not subject to allowance, has been revised to conform with the current presentation. Discussion of changes in the allowance The allowance for credit losses as of September 30, 2021 was $20.5 billion, a decrease from $30.8 billion at December 31, 2020. The decrease in the allowance for credit losses reflected: •an $8.0 billion reduction in consumer, predominantly in the credit card portfolio, reflecting improvements in the Firm's macroeconomic outlook; and •a $2.3 billion net reduction in wholesale, across the LOBs, reflecting improvements in the Firm's macroeconomic outlook. The COVID-19 pandemic has stressed many MEVs used in the Firm's allowance estimate which has created challenges in the use of modeled credit loss estimates, increased the reliance on management judgment, and resulted in adjustments to appropriately address the economic circumstances. These adjustments continued through the third quarter of 2021, although to a lesser extent than experienced during 2020. The U.S. economy has continued to improve despite the ongoing impact of the COVID-19 pandemic, with the benefits of vaccination resulting in improvements in the Firm's macroeconomic outlook, particularly in the adverse scenarios. However, uncertainties remain, including the impact that additional waves and variants of COVID-19 may have on the pace of economic growth, the strength of underlying labor markets with the expiration of government assistance programs, and the potential for changes in consumer behavior that could have longer term impacts on certain sectors. As a result of these uncertainties, the Firm retained meaningful weighting on its adverse scenarios in the third quarter of 2021, in line with the second quarter of 2021, but to a lesser extent than the fourth quarter of 2020. These adverse scenarios incorporate more punitive macroeconomic factors than the central case assumptions outlined below, resulting in a weighted average U.S. unemployment rate near 7% into the first quarter of 2022 and falling below 6% in the third quarter of 2022, and a weighted average cumulative change in U.S. GDP of 3.8% in the fourth quarter of 2022. The Firm’s central case assumptions reflected U.S. unemployment rates and U.S. real GDP as follows: Assumptions at September 30, 2021 4Q21 2Q22 4Q22 U.S. unemployment rate(a) 5.1 % 4.4 % 4.1 % Cumulative change in U.S. real GDP from 12/31/2019 3.3 % 5.0 % 6.2 % Assumptions at December 31, 2020 2Q21 4Q21 2Q22 U.S. unemployment rate(a) 6.8 % 5.7 % 5.1 % Cumulative change in U.S. real GDP from 12/31/2019 (1.9) % 0.6 % 2.0 % (a)Reflects quarterly average of forecasted U.S. unemployment rate. Subsequent changes to this forecast and related estimates will be reflected in the provision for credit losses in future periods.

Discussion of changes in the allowance Discussion of changes in the allowance The allowance for credit losses as of September 30, 2021 was $20.5 billion, a decrease from $30.8 billion at December 31, 2020. The decrease in the allowance for credit losses reflected: The allowance for credit losses as of September 30, 2021 was $20.5 billion, a decrease from $30.8 billion at December 31, 2020. The decrease in the allowance for credit losses reflected: •an $8.0 billion reduction in consumer, predominantly in the credit card portfolio, reflecting improvements in the Firm's macroeconomic outlook; and • an $8.0 billion reduction in consumer, predominantly in the credit card portfolio, reflecting improvements in the Firm's macroeconomic outlook; and •a $2.3 billion net reduction in wholesale, across the LOBs, reflecting improvements in the Firm's macroeconomic outlook. • a $2.3 billion net reduction in wholesale, across the LOBs, reflecting improvements in the Firm's macroeconomic outlook. The COVID-19 pandemic has stressed many MEVs used in the Firm's allowance estimate which has created challenges in the use of modeled credit loss estimates, increased the reliance on management judgment, and resulted in adjustments to appropriately address the economic circumstances. These adjustments continued through the third quarter of 2021, although to a lesser extent than experienced during 2020. The COVID-19 pandemic has stressed many MEVs used in the Firm's allowance estimate which has created challenges in the use of modeled credit loss estimates, increased the reliance on management judgment, and resulted in adjustments to appropriately address the economic circumstances. These adjustments continued through the third quarter of 2021, although to a lesser extent than experienced during 2020. The U.S. economy has continued to improve despite the ongoing impact of the COVID-19 pandemic, with the benefits of vaccination resulting in improvements in the Firm's macroeconomic outlook, particularly in the adverse scenarios. However, uncertainties remain, including the impact that additional waves and variants of COVID-19 may have on the pace of economic growth, the strength of underlying labor markets with the expiration of government assistance programs, and the potential for changes in consumer behavior that could have longer term impacts on certain sectors. As a result of these uncertainties, the Firm retained meaningful weighting on its adverse scenarios in the third quarter of 2021, in line with the second quarter of 2021, but to a lesser extent than the fourth quarter of 2020. These adverse scenarios incorporate more punitive macroeconomic factors than the central case assumptions outlined below, resulting in a weighted average U.S. unemployment rate near 7% into the first quarter of 2022 and falling below 6% in the third quarter of 2022, and a weighted average cumulative change in U.S. GDP of 3.8% in the fourth quarter of 2022.

    Organization, Consolidation and Presentation of Financial Statements [Abstract]                                     
        Basis of Presentation                                                                                           | Basis of presentation JPMorgan Chase & Co. (“JPMorgan Chase” or the “Firm”), a financial holding company incorporated under Delaware law in 1968, is a leading financial services firm based in the U.S., with operations worldwide. The Firm is a leader in investment banking, financial services for consumers and small businesses, commercial banking, financial transaction processing and asset management. Refer to Note 25 for a further discussion of the Firm’s business segments. The accounting and financial reporting policies of JPMorgan Chase and its subsidiaries conform to U.S. GAAP. Additionally, where applicable, the policies conform to the accounting and reporting guidelines prescribed by regulatory authorities. The unaudited Consolidated Financial Statements prepared in conformity with U.S. GAAP require management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expense, and the disclosures of contingent assets and liabilities. Actual results could be different from these estimates. In the opinion of management, all normal, recurring adjustments have been included such that this interim financial information is fairly stated. These unaudited Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements, and related notes thereto, included in JPMorgan Chase’s 2020 Form 10-K. Certain amounts reported in prior periods have been reclassified to conform with the current presentation, including certain deferred investment tax credits. In the first quarter of 2021 the Firm reclassified certain deferred investment tax credits from accounts payable and other liabilities to other assets to be a reduction to the carrying value of the associated tax-oriented investments. The reclassification also resulted in an increase in income tax expense and a corresponding increase in other income, with no effect on net income. Prior-period amounts have been revised to conform with the current presentation, including the Firm’s effective income tax rate. The reclassification did not change the Firm’s results of operations on a managed basis. Consolidation The Consolidated Financial Statements include the accounts of JPMorgan Chase and other entities in which the Firm has a controlling financial interest. All material intercompany balances and transactions have been eliminated. Assets held for clients in an agency or fiduciary capacity by the Firm are not assets of JPMorgan Chase and are not included on the Consolidated balance sheets. The Firm determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity. Refer to Notes 1 and 14 of JPMorgan Chase’s 2020 Form 10-K for a further description of JPMorgan Chase’s accounting policies regarding consolidation. Offsetting assets and liabilities U.S. GAAP permits entities to present derivative receivables and derivative payables with the same counterparty and the related cash collateral receivables and payables on a net basis on the Consolidated balance sheets when a legally enforceable master netting agreement exists. U.S. GAAP also permits securities financing activities to be presented on a net basis when specified conditions are met, including the existence of a legally enforceable master netting agreement. The Firm has elected to net such balances when the specified conditions are met. Refer to Note 1 of JPMorgan Chase’s 2020 Form 10-K for further information on offsetting assets and liabilities. Income tax expense The Firm’s effective tax rate was 17.2% and 19.1% for the three and nine months ended September 30, 2021, respectively, and 19.8% and 17.7% for the three and nine months ended September 30, 2020, respectively. The effective tax rate for the three and nine months ended September 30, 2021 reflects the recognition of an income tax benefit of $566 million related to finalizing the Firm’s 2020 U.S. federal tax return, which reduced the Firm’s effective tax rate by 4.0% and 1.2% respectively. The tax benefit included state and local impacts of federal tax method changes and a reduction in the valuation allowance for U.S. foreign tax credits.

In each transaction, a portion of the SMBS was acquired by third parties at the transaction date; the Firm acquired the remaining balance of those SMBS as trading securities. (b)Represents both the impact of changes in estimated future prepayments due to changes in market interest rates, and the difference between actual and expected prepayments.(c)Represents changes in prepayments other than those attributable to changes in market interest rates.(d)Represents amounts the Firm pays as the servicer (e.g., scheduled principal and interest, taxes and insurance), which will generally be reimbursed within a short period of time after the advance from future cash flows from the trust or the underlying loans. The Firm’s credit risk associated with these servicer advances is minimal because reimbursement of the advances is typically senior to all cash payments to investors. In addition, the Firm maintains the right to stop payment to investors if the collateral is insufficient to cover the advance. However, certain of these servicer advances may not be recoverable if they were not made in accordance with applicable rules and agreements.

Derivative receivables and payables, as well as the related cash collateral from the same counterparty, have been netted on the Consolidated balance sheets where the Firm has obtained an appropriate legal opinion with respect to the master netting agreement. Where such a legal opinion has not been either sought or obtained, amounts are not eligible for netting on the Consolidated balance sheets, and those derivative receivables and payables are shown separately in the tables below. In addition to the cash collateral received and transferred that is presented on a net basis with derivative receivables and payables, the Firm receives and transfers additional collateral (financial instruments and cash). These amounts mitigate counterparty credit risk associated with the Firm’s derivative instruments, but are not eligible for net presentation: •collateral that consists of liquid securities and other cash collateral held at third-party custodians, which are shown separately as "Collateral not nettable on the Consolidated balance sheets" in the tables below, up to the fair value exposure amount. For the purpose of this disclosure, the definition of liquid securities is consistent with the definition of high quality liquid assets as defined in the LCR rule;•the amount of collateral held or transferred that exceeds the fair value exposure at the individual counterparty level, as of the date presented, which is excluded from the tables below; and •collateral held or transferred that relates to derivative receivables or payables where an appropriate legal opinion has not been either sought or obtained with respect to the master netting agreement, which is excluded from the tables below.

        Current credit risk of derivative receivables and liquidity risk of derivative payables                         | The following table shows the aggregate fair value of net derivative payables related to OTC and OTC-cleared derivatives that contain contingent collateral or termination features that may be triggered upon a ratings downgrade, and the associated collateral the Firm has posted in the normal course of business, at September 30, 2021, and December 31, 2020.OTC and OTC-cleared derivative payables containing downgrade triggers(in millions)September 30, 2021December 31, 2020Aggregate fair value of net derivative payables$19,541 $26,945 (a)Collateral posted17,160 26,289 (a)Prior-period amount has been revised to conform with the current presentation.The following table shows the impact of a single-notch and two-notch downgrade of the long-term issuer ratings of JPMorgan Chase & Co. and its subsidiaries, predominantly JPMorgan Chase Bank, N.A., at September 30, 2021, and December 31, 2020, related to OTC and OTC-cleared derivative contracts with contingent collateral or termination features that may be triggered upon a ratings downgrade. Derivatives contracts generally require additional collateral to be posted or terminations to be triggered when the predefined threshold rating is breached. A downgrade by a single rating agency that does not result in a rating lower than a preexisting corresponding rating provided by another major rating agency will generally not result in additional collateral (except in certain instances in which additional initial margin may be required upon a ratings downgrade), nor in termination payments requirements. The liquidity impact in the table is calculated based upon a downgrade below the lowest current rating of the rating agencies referred to in the derivative contract.

Gains and losses were recorded in net interest income.(b)Excludes the amortization expense associated with the inception hedge accounting adjustment applied to the hedged item. This expense is recorded in net interest income and substantially offsets the income statement impact of the excluded components. Also excludes the accrual of interest on interest rate swaps and the related hedged items.(c)Primarily consists of hedges of the foreign currency risk of long-term debt and AFS securities for changes in spot foreign currency rates. Gains and losses related to the derivatives and the hedged items due to changes in foreign currency rates and the income statement impact of excluded components were recorded primarily in principal transactions revenue and net interest income.(d)Consists of overall fair value hedges of physical commodities inventories that are generally carried at the lower of cost or net realizable value (net realizable value approximates fair value). Gains and losses were recorded in principal transactions revenue. (e)The assessment of hedge effectiveness excludes certain components of the changes in fair values of the derivatives and hedged items such as forward points on foreign exchange forward contracts, time values and cross-currency basis spreads. Excluded components may impact earnings either through amortization of the initial amount over the life of the derivative, or through fair value changes recognized in the current period.(f)Represents the change in value of amounts excluded from the assessment of effectiveness under the amortization approach, predominantly cross-currency basis spreads. The amount excluded at inception of the hedge is recognized in earnings over the life of the derivative.

As a result of the application of hedge accounting, these inventories are carried at fair value, thus recognizing unrealized gains and losses in current periods. Since the Firm exits these positions at fair value, there is no incremental impact to net income in future periods.(b)Excludes hedged items where only foreign currency risk is the designated hedged risk, as basis adjustments related to foreign currency hedges will not reverse through the income statement in future periods. At September 30, 2021 and December 31, 2020, the carrying amount excluded for AFS securities is $12.6 billion and $14.5 billion, respectively, and for long-term debt is $11.8 billion and $6.6 billion, respectively.(c)Carrying amount represents the amortized cost, net of allowance if applicable. Refer to Note 9 for additional information.(d)Represents basis adjustments existing on the balance sheet date associated with hedged items that have been de-designated from qualifying fair value hedging relationships.(e)Positive amounts related to assets represent cumulative fair value hedge basis adjustments that will reduce net interest income in future periods. Positive (negative) amounts related to liabilities represent cumulative fair value hedge basis adjustments that will increase (reduce) net interest income in future periods.

The Firm has elected to measure certain instruments at fair value for several reasons including to mitigate income statement volatility caused by the differences between the measurement basis of elected instruments (e.g., certain instruments that otherwise would be accounted for on an accrual basis) and the associated risk management arrangements that are accounted for on a fair value basis, as well as to better reflect those instruments that are managed on a fair value basis. The Firm’s election of fair value includes the following instruments: •Loans purchased or originated as part of securitization warehousing activity, subject to bifurcation accounting, or managed on a fair value basis, including lending-related commitments •Certain securities financing agreements •Owned beneficial interests in securitized financial assets that contain embedded credit derivatives, which would otherwise be required to be separately accounted for as a derivative instrument •Structured notes, which are predominantly financial instruments that contain embedded derivatives that are issued as part of client-driven activities •Certain long-term beneficial interests issued by CIB’s consolidated securitization trusts where the underlying assets are carried at fair value Changes in fair value under the fair value option election The following table presents the changes in fair value included in the Consolidated statements of income for the three and nine months ended September 30, 2021 and 2020, for items for which the fair value option was elected. The profit and loss information presented below only includes the financial instruments that were elected to be measured at fair value; related risk management instruments, which are required to be measured at fair value, are not included in the table.

Difference between aggregate fair value and aggregate remaining contractual principal balance outstanding The following table reflects the difference between the aggregate fair value and the aggregate remaining contractual principal balance outstanding as of September 30, 2021, and December 31, 2020, for loans, long-term debt and long-term beneficial interests for which the fair value option has been elected.

(b)There were no performing loans that were ninety days or more past due as of September 30, 2021, and December 31, 2020, respectively. (c)Remaining contractual principal is not applicable to nonprincipal-protected structured notes and long-term beneficial interests. Unlike principal-protected structured notes and long-term beneficial interests, for which the Firm is obligated to return a stated amount of principal at maturity, nonprincipal-protected structured notes and long-term beneficial interests do not obligate the Firm to return a stated amount of principal at maturity, but for structured notes to return an amount based on the performance of an underlying variable or derivative feature embedded in the note. However, investors are exposed to the credit risk of the Firm as issuer for both nonprincipal-protected and principal-protected notes. (d)Where the Firm issues principal-protected zero-coupon or discount notes, the balance reflects the contractual principal payment at maturity or, if applicable, the contractual principal payment at the Firm’s next call date. At September 30, 2021, and December 31, 2020, the contractual amount of lending-related commitments for which the fair value option was elected was $16.9 billion and $18.1 billion, respectively, with a corresponding fair value of $(2) million and $(39) million, respectively. Refer to Note 28 of JPMorgan Chase’s 2020 Form 10-K, and Note 22 of this Form 10-Q for further information regarding off-balance sheet lending-related financial instruments.
